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.

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 test bed specifically, but is used in other testing.

Thank you to AMD for providing us with the R9 290X 4GB GPUs. These are MSI branded 'Gaming' models, featuring MSI's Twin Frozr IV dual-fan cooler design and military class components. Bundled with the cards is MSI Afterburner for additional overclocking, as well as MSI's Gaming App for easy frequency tuning.

The R9 290X is a second generation GCN card from AMD, under the Hawaii XT codename, and uses their largest Sea Islands GPU die at 6.2 billion transistors at 438mm2 built at TSMC using a 28nm process. For the R9 290X, that means 2816 streaming processors with 64 ROPs using a 512-bit memory bus to GDDR5 (4GB in this case). The official power rating for the R9 290X is 250W.

The MSI R9 290X Gaming 4G runs the core at 1000 MHz to 1040 MHz depending on what mode it is in (Silent, Gaming or OC), and the memory at 5 GHz. Displays supported include one DisplayPort, one HDMI 1.4a, and two dual-link DVI-D connectors.

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 Cooler Master for providing us with Nepton 140XL CLCs. The Nepton 140XL is Cooler Master's largest 'single' space radiator liquid cooler, and combines with dual 140mm 'JetFlo' fans designed for high performance, from 0.7-3.5mm H2O static pressure. The pump is also designed to be faster, more efficient, and uses thicker pipes to assist cooling with a rated pump noise below 25 dBA. The Nepton 140XL comes with mounting support for all major sockets, as far back as FM1, AM2 and 775.

Thank you to Corsair for providing us with an AX1200i PSU. The AX1200i was the first power supply to offer digital control and management via Corsair's Link system, but under the hood it commands a 1200W rating at 50C with 80 PLUS Platinum certification. This allows for a minimum 89-92% efficiency at 115V and 90-94% at 230V. The AX1200i is completely modular, running the larger 200mm design, with a dual ball bearing 140mm fan to assist high-performance use. The AX1200i is designed to be a workhorse, with up to 8 PCIe connectors for suitable four-way GPU setups. The AX1200i also comes with a Zero RPM mode for the fan, which due to the design allows the fan to be switched off when the power supply is under 30% load.

Thank you to Crucial for providing us with MX200 SSDs. Crucial stepped up to the plate as our benchmark list grows larger with newer benchmarks and titles, and the 1TB MX200 units are strong performers. Based on Marvell's 88SS9189 controller and using Micron's 16nm 128Gbit MLC flash, these are 7mm high, 2.5-inch drives rated for 100K random read IOPs and 555/500 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 320TB rated endurance with a three-year warranty.

Thank you to G.Skill for providing us with memory. G.Skill has been a long-time supporter of AnandTech over the years, for testing beyond our CPU and motherboard memory reviews. We've reported on their high capacity and high-frequency kits, and every year at Computex G.Skill holds a world overclocking tournament with liquid nitrogen right on the show floor. One of the most recent deliveries from G.Skill was their 4x16 GB DDR4-3200 C14 Kit, which we are planning for an upcoming review.

Thank you to Corsair for providing us with memory. Similarly, Corsair (along with PSUs) is also a long-time supporter of AnandTech. Being one of the first vendors with 16GB modules for DDR4 was a big deal, and now Corsair is re-implementing LEDs back on its memory after a long hiatus along with supporting specific projects such as ASUS ROG versions of the Dominator Platinum range. We're currently looking at our review pipeline to see when our next DRAM round-up will be, and Corsair is poised to participate.

    I stopped reading at the messy chart where Athlon X4 750 is available from 2 µArch and there is no science to naming. AMD's CPU division was a bigger failure than its GPU division and it still it. I used to have 3 AMD systems at the same time back in 2005 but have steadily moved away and was considering replacing the last AMD system (Phenom II 840) using Prime Day sales. Reply

    The 750 and 750K are two different SKUs. As mentioned, trying to find the 750 at retail (and in stock) is *really difficult*, and I'd probably point to it being an OEM-only SKU for a certain design. If anyone has a 750/can find one, let me know. Reply
  • artk2219 - Wednesday, July 20, 2016 - link

    I found a link for one, but I think its just an OEM one, and it's from Aliexpress, so it may take a while to get to you. I hope I could help!

    I don't think poignant is the word you are looking for here. That would be something that makes you very sad, or emotionally touches you deeply. Reply
  • wallysb01 - Thursday, July 14, 2016 - link

    I guess I don't totally understand the comparison to the G3258. I know its a fairly popular processor (I have its non-overclockable little brother, the G3250, and love it in a simple home office set up that I use occasionally for light gaming too). However, its 2 years old. Where is the G4500 or G4520? Supposedly the skylake Pentium would be about 10% faster than haswell, no? And with some perf/W gains too?

    Speaking of which, where's the comparison to Intel in the power consumption? Do I just not want to see that? If in these multithreaded tasks the 845 is chugging along using 80-85 W, while the Intel parts are still near their stated TDP, it more or less invalidates the small performance gain of the AMD chip in those tasks. Looking back at the skylake review, it seems at load the Intel chips might be using anything from 0-20% more than their TDP, this AMD chip is going 30% above.

    I'd love it if AMD could push intel into offering more cores at lower price points, but this doesn't seem good enough to do that....

    Tacking on a G4500 is not terribly pertinent to the task at hand and they are just using archived results here. The comparison from the 2 i3 parts should give you an idea of relative performance. Otherwise, I'm surprised we get such an in depth review from an hollowed out Anandtech.

    You are confusing TDP with total system draw.

    You have a "four core" CPU here for $70, what more do you want? They soundly thrash the dual-core Pentiums and i3s in some well parallelized applications. The problem is the world isn't well parallelized and the CPUs don't have 4 real cores which is why you have i3s still competitive 8 core FX chips.

    WOW. This is an amazing work. It does explain too much about AMD's Bulldozer versions. It does explain why AMD doesn't bother to bring the full Carrizo line in desktop. It does show, at least from my perspective, that Bulldozer architecture was not a bad architecture to begin with, but a dead end from the beginning. Reply
  • artk2219 - Thursday, July 14, 2016 - link

    Sigh, poor Llano and your FM1 package, always forgotten. Granted it was the last of the stars cores, and not a bulldozer derivative, but it would still be nice to see it included with its brethren. Reply
  • TheinsanegamerN - Thursday, July 14, 2016 - link

    The last of AMD's good cores. Mobile Llano was fantastic for OCing and undervolting. Reply
  • artk2219 - Thursday, July 14, 2016 - link

    Indeed it was/is, my fiance is still using my old Asus K53TA. I overclocked the A6 (back when A6's came with 4 cores) in that laptop to run at 2.4 instead of 1.4 for the base, and the turbo to 3Ghz. while overclocking i was able to undervolt at base clocks, and slightly overvolt the turbo clocks. In effect I got better battery life and waaayyyy better performance by just spending a little time playing with the P-States. I still think thats one of the best laptops I've ever owned in terms of reliability and capability, if only it weren't so clunky. Sigh, well you cant have it all.
