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 our 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 Sapphire for providing us with several of their AMD GPUs. We met with Sapphire back at Computex 2016 and discussed a platform for our future testing on AMD GPUs with their hardware for several upcoming projects. As a result, they were able to sample us the latest silicon that AMD has to offer. At the top of the list was a pair of Sapphire Nitro R9 Fury 4GB GPUs, based on the first generation of HBM technology and AMD’s Fiji platform. As the first consumer GPU to use HDM, the R9 Fury is a key moment in graphics history, and this Nitro cards come with 3584 SPs running at 1050 MHz on the GPU with 4GB of 4096-bit HBM memory at 1000 MHz.

Following the Fury, Sapphire also supplied a pair of their latest Nitro RX 480 8GB cards to represent AMD’s current performance silicon on 14nm (as of March 2017). The move to 14nm yielded significant power consumption improvements for AMD, which combined with the latest version of GCN helped bring the target of a VR-ready graphics card as close to $200 as possible. The Sapphire Nitro RX 480 8GB OC graphics card is designed to be a premium member of the RX 480 family, having a full set of 8GB of GDDR5 memory at 6 Gbps with 2304 SPs at 1208/1342 MHz engine clocks.

With the R9 Fury and RX 480 assigned to our gaming tests, Sapphire also passed on a pair of RX 460s to be used as our CPU testing cards. The amount of GPU power available can have a direct effect on CPU performance, especially if the CPU has to spend all its time dealing with the GPU display. The RX 460 is a nice card to have here, as it is powerful yet low on power consumption and does not require any additional power connectors. The Sapphire Nitro RX 460 2GB still follows on from the Nitro philosophy, and in this case is designed to provide power at a low price point. Its 896 SPs run at 1090/1216 MHz frequencies, and it is paired with 2GB of GDDR5 at an effective 7000 MHz.

We must also say thank you to MSI for providing us with their GTX 1080 Gaming X 8GB GPUs. Despite the size of AnandTech, securing high-end graphics cards for CPU gaming tests is rather difficult. MSI stepped up to the plate in good fashion and high spirits with a pair of their high-end graphics. The MSI GTX 1080 Gaming X 8GB graphics card is their premium air cooled product, sitting below the water cooled Seahawk but above the Aero and Armor versions. The card is large with twin Torx fans, a custom PCB design, Zero-Frozr technology, enhanced PWM and a big backplate to assist with cooling.  The card uses a GP104-400 silicon die from a 16nm TSMC process, contains 2560 CUDA cores, and can run up to 1847 MHz in OC mode (or 1607-1733 MHz in Silent mode). The memory interface is 8GB of GDDR5X, running at 10010 MHz. For a good amount of time, the GTX 1080 was the card at the king of the hill.

Thank you to ASUS for providing us with their GTX 1060 6GB Strix GPU. To complete the high/low cases for both AMD and NVIDIA GPUs, we looked towards the GTX 1060 6GB cards to balance price and performance while giving a hefty crack at >1080p gaming in a single graphics card. ASUS offered a hand here, supplying a Strix variant of the GTX 1060. This card is even longer than our GTX 1080, with three fans and LEDs crammed under the hood. STRIX is now ASUS’ lower cost gaming brand behind ROG, and the Strix 1060 sits at nearly half a 1080, with 1280 CUDA cores but running at 1506 MHz base frequency up to 1746 MHz in OC mode. The 6 GB of GDDR5 runs at a healthy 8008 MHz across a 192-bit memory interface.

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 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.

    On the first page, I assume the green highlight in the processor charts signifies an advantage for that side. Why are the cores/threads rows in the Ryzen side not highlighted? Or is 8/16 not better than 4/8? Reply

    intel must really push money into anandtech. :) so many interesting things to report about and they spend time on a niche product..... Reply

    This has been in the works for a while because our CPU failed. I work on the CPU stuff - other editors work on other things ;) If you've got an idea, reach out to us. I can never guarantee anything (I've got 10+ ideas that I don't have time to do) but if it's interesting we'll see what we can do. Plus it helps us direct what other content we should be doing. Reply

    This is an amazing amount of benchmarking with many options. thank you. Must have been a lot of work :-)
    The obvious idea is this:

    Gaming (modern CPU limited and most played games) & Productive work (rendering, encoding, 4K video work, R/statistics/Matlab)

    Test those under 4c/8t and 8c/16t CPUs both from AMD and Intel - all at most common non-esoteric overlock levels (+/-10%).

    This is what many of your readers want:

    How much does c. 5Ghz 4c/8t do vs 4.x Ghz 8c/16t when taken to it's everyday stable extreme, in modern games / productivity.

    The web is already full of benchmarks at stock speed. Or overclocked Ryzen R 7 against stock Intel, or OC intel against overclocked Ryzen - and the game/app selections are not very varied.

    The result is a simple graph that plots the (assumed) linear trend in performance/price and shows any deviations below/above the linear trend.

    Of course, if you already have the Coffee lake 6c/12t sample, just skip the 4c/8t and go with 6c/12t vs 8c/16 comparision.

    Thanks for all the hard work throughout all these years!

    "so many interesting things to report about and they spend time on a niche product....."

    What can we say? CPUs have been our favorite subject for the last 20 years.=)

    "For 2017, Intel is steering the ship in a slightly different direction, and launching the latest microarchitecture on the HEDT platform."

    Skylake-S, Kaby Lake-S and Kaby Lake-X share the same microarchitecture, right?
    Then Skylake-X is newer microarchitecture than Kaby Lake-X (changes to L2 and L3 caches, AVX-512).
  • Ian Cutress - Monday, July 24, 2017 - link

    Correct me if I'm wrong: SKL-SP cores are derived from SKL-S, and 14nm. KBL-S/X are 14+, and shares most of its design with SKL-S, and the main changes are power related. Underneath there's no real performance (except Speed Shift v2), but Intel classifies Kaby Lake as its latest non-AVX512 IPC microarchitecture. Reply
  • user_5447 - Monday, July 24, 2017 - link

    Kaby Lake-S has some errata fixes compared to Skylake-S. AFAIK, this is the only change to the CPU core (besides the Speed Shift v2, if it even involved hardware changes).
    David Kanter says Skylake-X/EP is 14+ nm http://www.realworldtech.com/forum/?threadid=16889...

    I have a buddy who works in the fabs -- SKL-X is still on plain 14nm Reply
