After all, even Intel is moving away from CPU-only approach with its upcoming Xeon Phi.
#FURY X FP64 CODE#
To see TFLOPS on one side, and GFLOPS on another is a clear defeat for the CPU strategy, and running a CPU-0nly code is starting to look archaic. And no, Broadwell-E in 2016 and Skylake-E in 2017 won’t change the performance significantly.

And mind you, this is a 3.6 GHz octa-core i7 5960X with four channels of DDR4-2400 CL14 (theoretical: 76.8GB/s), and souped-up 3.2 GHz uncore! Even when running the native code with full AVX2 FMA support, the difference is still like two orders of magnitude (10x, 100x). Wow… the difference approaches hundreds of times (not percent!) in the favour of GPU when running OpenCL code neck-to-neck. Here you can see a summary of single precision GPU only OpenCL, GPU+CPU OpenCL (where available), CPU only OpenCL, and CPU only native code. SiSoft Sandra 2015 SP3 Scientific Test – showing clear difference between the world’s most powerful consumer CPU and GPU. Knowing this is a consumer version nevertheless, without full OpenGL or fully enabled hardware double precision FP, I wanted to try the core number crunching capability of the chip and HBM without relying on the commercial apps which may prefer double precision, yet abstain from SuperPI type little routines. Once AMD goes ahead with its professional, HPC server versions of this platform, a passive air cooled version will be a must – or a flavour with just a local pump module on the card, to be connected via daisy chain to a rack-wide liquid cooling system. It’s a shame you cannot buy the PCB alone, or PCB with a DIY waterblock, akin to what EVGA goes to NVIDIA cards. If you’re looking for a multi-GPU setup, perhaps you should consider buying a 3rd party liquid cooled system, such as Thermaltake DIY section, Swiftec, Aqua Cooling, or EK-Waterblocks. Every Radeon R9 Fury X has its own cooling loop, with 120mm fan at the other end. The cons? Well, find another spare position for that integrated radiator and fan to fit in. The difference is especially obvious in a cramped, cable-rich system as our test configuration. We paired Gigabyte’s X99 Gaming G1 top end mainboard with Intel current high-end, Core i7 5960X (Haswell-E) processor and Thermaltake liquid cooling for the processor, all packed inside the Antec chassis. The shortened card makes insertion into a system a breeze, even if you want to put 2 or 3 of them. The integrated liquid cooling has its pros and cons, of course. Depending on a card you have at hand, you could clock the HBM memory to 650MHz, and achieve massive bandwidth of 691.2 GB/s, faster than AMD’s dual-GPU card of yesteryear (R9 295X2 had 640GB/s) or Nvidia GeForce GTX Titan Z (672 GB/s). In our case, we managed to get 575 MHz stable, resulting in bandwidth going to impressive 589 GB/s. Still, even though AMD does not allow it, you can overclock the memory if you know how. Right now, AMD does not allow (officially) overclock the integrated 3-D HBM memory for some extra bandwidth too, essential in the scientific and technical computation. I’ve got a decent, stable 9% to 10% overclock that passes all the HPC math benches with flying colours. Thirdly, the GPU overclocks lovely – and we don’t mean frames per second in games. Firstly, it was by far physically the smallest high-end graphics card in, say, a decade? Thank you integrated liquid cooling – with or without the slight noise heard in the Cooler Master’s earlier revisions of the cooling pump.įollowing a small modification, you can push both GPU and HBM RAM inside AMD Catalyst – and both show great promise. In the world where fast processing and low latency means serious money, does AMD have a chance to shine?Įver since getting our hands on AMD’s newest gaming top of the line GPU, there was a feeling that this is something special.
And AMD (theoretically) has the highest performing piece of silicon of all times – 8.9 billion transistors, 8.6 SP TFLOPS and once unlocked, massive 4.3 TFLOPS Double-Precision (535 GFLOPS DP in this consumer-focused version).

The focus of this article however, is its potential and usage in applications where Fiji GPU will be branded as Fire Pro, and Fire Pro S (Server) – where AMD can take an ASIC and upsell it to commercial clients, with full-speed enabled for Double Precision floating point operations. And while the first results forced Nvidia to launch “Titan Lite” in the form of GeForce GTX 980 Ti, DirectX 12 benchmarks are starting to show different, brighter outlook for AMD, starting with Ashes of the Singularity. When AMD launched its Fiji-based graphics cards, all eyes were focused on its performance in consumer applications such as computer games.
