Test Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

Power Consumption
For our power consumption testing, we place the system under a heavy Prime95 load and then take the power consumption reading from the internal CPU sensor. This is the sensor that determines power resources on the system, as well as how fan speeds and throttling should be adjusted. On most platforms we get a breakdown of chip-wide power compared to core power and memory controller power, however the Skylake-SP platform has all that removed and we can only get full-chip power. We also test on a per-core level.
At full load, all of our Xeon W chips are underneath TDP, despite running at full core turbo. The Xeon W-2102 and Xeon W-2104 really show that these quad-core parts are certainly well below the 120W rating. When we look at the higher core count Xeon W parts, we see that the power consumption is well below the corresponding Core i9 processors - the Xeon W-2195 for example is only 123W, compared to 162W for the Core i9 version.
If we look at the chips when only a single thread is loaded, then the Xeon W chips spread out a bit more. The AMD parts fare better here compared to the W-2195, but the W-2195 is still below the Core i9 parts.
Many thanks to...
We must thank the following companies for kindly providing hardware for our multiple test beds. Some of this hardware is not in this testbed specifically but is used in other testing.
Thank you to ASUS for providing us with GTX 980 Strix GPUs. At the time of release, the STRIX brand from ASUS was aimed at silent running, or to use the marketing term: '0dB Silent Gaming'. This enables the card to disable the fans when the GPU is dealing with low loads well within temperature specifications. These cards equip the GTX 980 silicon with ASUS' Direct CU II cooler and 10-phase digital VRMs, aimed at high-efficiency conversion. Along with the card, ASUS bundles GPU Tweak software for overclocking and streaming assistance.
The GTX 980 uses NVIDIA's GM204 silicon die, built upon their Maxwell architecture. This die is 5.2 billion transistors for a die size of 298 mm2, built on TMSC's 28nm process. A GTX 980 uses the full GM204 core, with 2048 CUDA Cores and 64 ROPs with a 256-bit memory bus to GDDR5. The official power rating for the GTX 980 is 165W.
The ASUS GTX 980 Strix 4GB (or the full name of STRIX-GTX980-DC2OC-4GD5) runs a reasonable overclock over a reference GTX 980 card, with frequencies in the range of 1178-1279 MHz. The memory runs at stock, in this case, 7010 MHz. Video outputs include three DisplayPort connectors, one HDMI 2.0 connector, and a DVI-I.

Thank you to Crucial for providing us with MX300 SSDs. Crucial stepped up to the plate as our benchmark list grows larger with newer benchmarks and titles, and the 1TB MX300 units are strong performers. Based on Marvell's 88SS1074 controller and using Micron's 384Gbit 32-layer 3D TLC NAND, these are 7mm high, 2.5-inch drives rated for 92K random read IOPS and 530/510 MB/s sequential read and write speeds.
The 1TB models we are using here support TCG Opal 2.0 and IEEE-1667 (eDrive) encryption and have a 360TB rated endurance with a three-year warranty.

Thank you to Corsair for providing us with Vengeance LPX DDR4 Memory, HX750 Power Supply, and H115i CPU Cooler.
Corsair kindly sent a 4x8GB DDR4 2666 set of their Vengeance LPX low profile, high-performance memory for our stock testing. The heatsink is made of pure aluminum to help remove heat from the sticks and has an eight-layer PCB. The heatsink is a low profile design to help fit in spaces where there may not be room for a tall heat spreader; think a SFF case or using a large heatsink. Timings on this specific set come in at 16-18-18-35. The Vengeance LPX line supports XMP 2.0 profiles for easily setting the speed and timings. It also comes with a limited lifetime warranty.
Powering the test system is Corsair's HX750 Power Supply. This HX750 is a dual mode unit able to switch from a single 12V rail (62.5A/750W) to a five rail CPU (40A max ea.) and is also fully modular. It has a typical selection of connectors, including dual EPS 4+4 pin four PCIe connectors and a whopping 16 SATA power leads, as well as four 4-pin Molex connectors.
The 135mm fluid dynamic bearing fan remains off until it is 40% loaded offering complete silence in light workloads. The HX750 comes with a ten-year warranty.
In order to cool these high-TDP HEDT CPUs, Corsair sent over its latest and largest AIO in the H115i. This closed-loop system uses a 280mm radiator with 2x140mm SP140L PWM controlled fans. The pump/block combination mounts to all modern CPU sockets. Users are also able to integrate this cooler into the Corsair link software via USB for more control and options.
Thank You to Kingston for sampling us some DDR4-2666 C19 RDIMM Memory.
Xeon W processors support RDIMM ECC memory, and our motherboard here would not accept UDIMMs, and Kingston kindly supplied the memory needed. The (KSM26RS8/8HAI) modules were faultless in our testing.

He was an Intel fanboy undercover as an AMD shill who's in Intel's pocket.He's a triple agent.
The only way to keep is cover is to not show bias, be objective and report the facts as they stand, otherwise his employers will figure out he's turned (and turned and turned) and they'll cut him loose.
True story.

Anandateers,As a Xeon / workstation user for many years, this is an interesting review, but seems eccentric to typical workstation buyers' tendencies.
There are three kinds of Xeon users based on the emphasis in applications: one, single thread performance such as 3D modeling, animation, and simulation, two, multi-threaded which includes CPU rendering, some well-threaded simulation, some aspects of video and photo-editing, and database, computational application, and three, a very common one in which the workstation has to be reasonably good at both single-threaded and multi-threaded. Solidworks is very useful to evaluate workstations as it's well-written and also demanding of both very high single and multi-thread performance. If you look at worsktation listings, the modeling units are i7-8800K A lot of Solidworks modelers are running i7-8800K systems- with the required Quadro. ECC is not as universal as it was five years ago. But, if the system is also used for the very well-threaded Solidworks rendering, they will use 10 or 12-core i7 or i9 that have high Turbo clock speeds.
My solution to reasonable performance in both single and multi-threaded work is a Xeon E5-1680 v2 which I run at 4.3GHz on all 8 cores. Yes, you can overclock E5-1680 v2, E5-1660 v2, and E5-1650 v2. A friend of mine using Solidworks and Maya runs an E5-1680 v2 at 4.7GHz using a large custom-designed external cooling tower. Because a fast 8-core is the sweet spot in single and multi- thread balance, I'm sorry the review did not include tests of the Xeon W2145 (8C@3.7/4.5), also the W2135 (6C@3.7/4.5), and especially, the i7-7820X (8C@3.6/4.3) overclockable- there are a lot of 4.6-4.8GHz on Passmark and it's under $600 as compared to $1100 for the W-2145. The i7-7820X could be the perfect workstation CPU except for the limited PCIe lanes. The W-2145 has an excellent average single threaded mark of 2537 on Passmark, but that has a locked multiplier. The i7-7820X however at 4.8GHz has a calculated single thread up to 3100 and the top performer on Passmark at about 3185. This is even more interesting in comparison to the recent AMD Ryzen 2700X which has greatly improved Ryzen single thread performance. However, the highest CPU rating in Passmark calculates to about 2600- still really excellent: the average i7-7700K is 2583. The 2700X is tempting from a cost/performance standpoint, but those needing the highest possible single-threaded performance will stay with Intel.
Overall I'm very glad to see a review of Xeon W's, but in my view, the inclusion of the low end OEM 4-core models, the inclusion of the limited issue i7-8086K and the obsolete i7-7700k instead of the i7-8800K, plus the exclusion of the 8-core Xeon W-2145 and it's i7 counterpart i7-7820X makes it less useful to the typical workstation buyer. Some comparative tasks within workstation applications would be more informative too than synthetic benchmarks.

P.S. In my view, Intel is making a huge mistake with the upcoming i9-9700K. It's 8-core and has high clock speeds- 3.6/4.9GHz and will be overclockable, but minus hyperthreading is going to send many, many workstation buyers to whatever the Ryzen 2800X turns out to be. The lack of hyperthreading will make it a gaming-only CPU and what games will make much if any use of all 8 cores?

You mean i7-8700K, but yeah.A good workstation has more cores (and PCIe lanes) than desktop, but still good single-thread perf. It's mostly servers where you really care about aggregate performance more than single-thread.

Some comparative tasks within workstation applications would be more informative too than synthetic benchmarks.1) Unfortunately these were the only 5 SKUs we were able to get ahold of. Please pester Intel if you want to see more reviewed.
2) We have many other CPUs tested in our database, www.anandtech.com/Bench
3) We can't test every overclockable CPU at every frequency. Overclocking is in itself a niche (as much as people talk about it online, and we only pull out OC data unless it's universal: Running our suite CPU X at Frequencies YXZ just multiplies our testing time.
4) Benchmarks: I've repeatedly asked in reviews over the years for users to get in contact with their preferred professional benchmarks. Some ideas were good (Agisoft, DigiCortex), some were not (licensable software doesn't scale over 5 systems testing simultaneously). But please keep emailing suggestions.
Please bear in mind, not 100% of benchmarks have to be specifically for you. I get so many complaints about 'why include benchmark X?' because it doesn't pertain to that user. There are other users who prefer other benchmarks. Even if 50% or 20% of the benchmarks are relevant to you, that's the take-home data for you, not the others. The others are for other people. Don't expect 100% of all the data points to be relevant for you.

Have you looked into using SPECviewperf 13 for testing? It's probably the best all-in-one suite for workstation performance.BambiBoom - Tuesday, July 31, 2018 - link
Ian Cutress,I don't expect any review to have any particular content specific to me and don't understand your creating that inference.
My point was that the review was less relevant to buyers considering Xeon W's by omitting an important category of processors, the fast 6-core and moreso the W-2145 8-core. As those processors were unavailable, we'll look forward to seeing something about them perhaps another time.
It seems that those buying HP, Dell, Lenovo, Boxx, and Puget systems are going to buy quite a few W-2123, W-2125, W-2135, W-2145 plus the i7-and i9 alternatives including i7-8700K and i7-7820X and I would have liked to have seen those reviewed. Those with $2,000 can have good performance in both in 10, 12 and greater core count CPU's, but the 8-core is important in having a good balance at a comfortable cost. Tests have shown- e.g. the Puget Systems articles that demonstrate that multi-threaded applications often (e.g. Adobe) have peak core utiltization at 5-6 cores and so a fast 8- core is a good solution. As the Xeon W-2145 and i7-7820X are both 8-cores @ 3.7/4.5, it seemed that would be a good "center" for a Xeon W- review. I also don't expect a review to try every overclocked CPU, but in the example of comparing the W-2145 and i7-7820X, it seems interesting to note that the i7-7820X may be run at 4.8GHz for $500 less (-45%) than the 4.5GHz W-1245.
You seem to have stored up a good supply of impatience and anger towards readers making requests or suggestions. Keep in mind we're not as expert, have the range of technical or market knowledge, nor access to so many components as do you. Do you enjoy this work?

"You seem to have stored up a good supply of impatience and anger towards readers making requests or suggestions." You have to empathize with Ian, and the other reviewers. With every article / review they publish here there seems to be a small cadre of users that will criticize everything they write, deride them, belittle them. After a time it gets old, and starts to weigh heavily. All while working under intense pressure from deadlines.Constructive criticism is a thing most people should read into. In my job as a photographer / trainer, the basic idea is "Okay, this is what is good about the image, this is what is wrong and here is how to improve upon it in the future." While your comment had much of the workings for a proper CC, I also don't see Ian's anger or impatience. I only see him reiterating a point he's had to make dozens of times.
0ldman79 - Tuesday, July 31, 2018 - link
Agreed.I've seen where Ian was getting irritated, this didn't appear to be one of those moments.
BambiBoom - Wednesday, August 1, 2018 - link
imediaphotography,As Anandtech is owned by Purch Group which has a marketing function; "to better reflect its growing portfolio of brands and products focused on purchasing decisions", one would think that mentioning median level products not reviewed but that were, in my view, probably more likely to be purchased by workstation buyers would have had a better reception. Instead of addressing the specifics of the content and intention of my comments, Ian's reply was almost entirely a general rant as to readers' unfair comments and those applied applied to me.
Reviewers/ critics that take every comment personally seem unhappy in their work. Yes, reviewing is difficult and under pressure of deadlines, but your idea of focusing on constructive criticism is the proper mode of response. In a professional media situation, applying general irritation based on past experience to an individual has no excuse. Ian could have simply said that the processors missing from the review would be reviewed when available and not use most of his comments repeating that I insist every review revolve around me.
I've been a reviewer / critic, having had a radio program in Los Angeles for six years. During that run I became used to criticism of my choices for review and comments, and once in a while this was vehement. I once had a fellow make semi-obscene comments and implied threats concerning something I said- about Mozart. Still, my perplexity and pique was never applied to any other caller.

To me it looks like forcibly introducing an i9 SKU and it's need for differentiation with an i7 messed up the whole lineup.If they had stuck with the traditional lineup, then we could have had 8/16 i7, 6/12 i5, and 4/8 i3 and the entire line would have been much better across the board.
