An interesting night of testing

Last night I did our first ever live benchmarking session using the just-arrived Radeon Vega Frontier Edition air-cooled graphics card. Purchased directly from a reseller, rather than being sampled by AMD, gave us the opportunity to testing for a new flagship product without an NDA in place to keep us silenced, so I thought it would be fun to the let the audience and community go along for the ride of a traditional benchmarking session. Though I didn’t get all of what I wanted done in that 4.5-hour window, it was great to see the interest and excitement for the product and the results that we were able to generate.

But to the point of the day – our review of the Radeon Vega Frontier Edition graphics card. Based on the latest flagship GPU architecture from AMD, the Radeon Vega FE card has a lot riding on its shoulders, despite not being aimed at gamers. It is the FIRST card to be released with Vega at its heart. It is the FIRST instance of HBM2 being utilized in a consumer graphics card. It is the FIRST in a new attempt from AMD to target the group of users between gamers and professional users (like NVIDIA has addressed with Titan previously). And, it is the FIRST to command as much attention and expectation for the future of a company, a product line, and a fan base.

Other than the architectural details that AMD gave us previously, we honestly haven’t been briefed on the performance expectations or the advancements in Vega that we should know about. The Vega FE products were released to the market with very little background, only well-spun turns of phrase emphasizing the value of the high performance and compatibility for creators. There has been no typical “tech day” for the media to learn fully about Vega and there were no samples from AMD to media or analysts (that I know of). Unperturbed by that, I purchased one (several actually, seeing which would show up first) and decided to do our testing.

On the following pages, you will see a collection of tests and benchmarks that range from 3DMark to The Witcher 3 to SPECviewperf to LuxMark, attempting to give as wide a viewpoint of the Vega FE product as I can in a rather short time window. The card is sexy (maybe the best looking I have yet seen), but will disappoint many on the gaming front. For professional users that are okay not having certified drivers, performance there is more likely to raise some impressed eyebrows.

Radeon Vega Frontier Edition Specifications

Through leaks and purposeful information dumps over the past couple of months, we already knew a lot about the Radeon Vega Frontier Edition card prior to the official sale date this week. But now with final specifications in hand, we can start to dissect what this card actually is.

The Vega FE shares enough of a specification listing with the Fury X that it deserves special recognition. Both cards sport 4096 stream processors, 64 ROPs and 256 texture units. The Vega FE is running at much higher clock speeds (35-40% higher) and also upgrades to the next generation of high-bandwidth memory and quadruples capacity. Still, there will be plenty of comparisons between the two products, looking to measure IPC changes from the CUs (compute units) from Fiji to the NCUs built for Vega.

The Radeon Vega GPU

The clock speeds also see another shift this time around with the adoption of “typical” clock speeds. This is something that NVIDIA has been using for a few generations with the introduction of GPU Boost, and tells the consumer how high they should expect clocks to go in a nominal workload. Normally I would say a gaming workload, but since this card is supposedly for professional users and the like, I assume this applies across the board. So even though the GPU is rated at a “peak” clock rate of 1600 MHz, the “typical” clock rate is 1382 MHz. (As an early aside, I did NOT see 1600 MHz in any of my testing time with our Vega FE but did settle in a ~1440 MHz clock most of the time.)

Go west young researcher! AMD's Radeon Vega Frontier Edition is available now

Subject: Graphics Cards | June 27, 2017 - 06:51 PM |
Tagged: Vega FE, Vega, HPC, amd

AMD have released their new HPC card, the Radeon Vega Frontier Edition, which Jim told you about earlier this week.  The air cooled version is available now, with an MSRP of $999USD followed by a water-cooled edition arriving in Q3 with price tag of $1499.

The specs they list for the cards are impressive and compare favourably to NVIDIA's P100 which is the card AMD tested against, offering higher TFLOPS for both FP32 and FP16 operations though the memory bandwidth lags a little behind.

The memory size for the Vega is interesting, HBC is AMDs High Bandwidth Cache Controller which not only uses the memory cache more effectively but is able to reach out to other high performance system memory for help.  AMD states that the Radeon Vega Frontier Edition has the capability of expanding traditional GPU memory to 256TB; perhaps allowing new texture mods for Skyrim or Fallout!  Expect to see more detail on this feature once we can get our hands on a card to abuse, nicely of course.

AMD used the DeepBench Benchmark to provide comparative results, the AMD Vega FE system used a dual socketed system with Xeon E5 2640v4s @ 2.4Ghz 10C/20T, 32GB DDR4 per socket, on Ubuntu 16.04 LTS with ROCm 1.5, and OpenCL 1.2, the NVIDIA Tesla P100 system used the same hardware with the CuDNN 5.1, Driver 375.39 and Cuda version 8.0.61 drivers.  Those tests showed the AMD system completing the benchmark in 88.7ms, the Tesla P100 completed in 133.1 ms, quite an impressive lead for AMD.  Again, there will be much more information on performance once the Vega FE can be tested.
