Intel Graphics

What is “CofeeLake” CFL? The 8th generation Intel Core architecture is code-named “CofeeLake” (CFL): unlike previous architectures, it is a minor stepping of the previous 7th generation “KabyLake” (KBL), itself a minor update of the 6th generation “SkyLake” (SKL). As before, the CPUs contain an integrated GPU (with compute support … Read more…

nVidia Titan V: Volta GPGPU performance in CUDA and OpenCL

What is “Titan V”? It is the latest high-end “pro-sumer” card from nVidia with the next-generation “Volta” architecture, the next generation to the current “Pascal” architecture on the Series 10 cards. Based on the top-end 100 chipset (not lower 102 or 104) it boasts full speed FP64/FP16 performance as well … Read more…

nVidia Titan X: Pascal GPGPU Performance in CUDA and OpenCL

What is “Titan X (Pascal)”? It is the current high-end “pro-sumer” card from nVidia using the current generation “Pascal” architecture – equivalent to the Series 10 cards. It is based on the 2nd-from-the-top 102 chipset (not the top-end 100) thus it does not feature full speed FP64/FP16 performance that is … Read more…

AMD Ryzen+ 2700X, 2600 Review & Benchmarks – 2-channel DDR4 Cache & Memory Performance

What is “Ryzen+” ZEN+? After the very successful launch of the original “Ryzen” (Zen/Zeppelin – “Summit Ridge” on 14nm), AMD has been hard at work optimising and improving the design: “Ryzen+” (code-name “Pinnacle Ridge”) is thus a 12nm die shrink that can also includes APU – with integrated “Vega RX” … Read more…

AVX512 Improvement for Skylake-X (Core i9-9700X)

Intel Skylake-X Core i9

What is AVX512? AVX512 (Advanced Vector eXtensions) is the 512-bit SIMD instruction set that follows from previous 256-bit AVX2/FMA3/AVX instruction set. Originally introduced by Intel with its “Xeon Phi” GPGPU accelerators – albeit in a somewhat different form – it has finally made it to its CPU lines with Skylake-X … Read more…

NUMA performance improvement for AMD ThreadRipper in Sandra SP2

What is NUMA? Modern CPUs have had a built-in memory controller for many years now, starting with the K8/Opteron, in order to higher better bandwidth and lower latency. As a result in SMP systems each CPU has their own memory controller and its own system memory that it can access … Read more…

AMD Threadripper 1950X Review & Benchmarks – CPU 16-core/32-thread Performance

What is “Threadripper”? “Threadripper” (code-name ZP aka “Zeppelin”) is simply a combination of inter-connected Ryzen dies (“nodes”) on a single socket (TR4) that in effect provide a SMP system-on-a-single-socket – without the expense of multiple sockets, cooling solutions, etc. It also allows additional memory channels (4 in total) to be … Read more…

Intel Skylake-X Core i9

What is “SKL-X”? “Skylake-X” (E/EP) is the server/workstation/HEDT version of desktop/mobile Skylake CPU – the 6-th gen Core/Xeon replacing the current Haswell/Broadwell-E designs. It naturally does not contain an integrated GPU but what does contain is more cores, more PCIe lanes and more memory channels (up to 6 64-bit) for … Read more…

FP16 GPGPU Image Processing Performance & Quality

GPGPU Image Processing

What is FP16 (“half”)? FP16 (aka “half” floating-point) is the IEEE lower-precision floating-point representation that has recently begun to be supported by GPGPUs for compute (e.g. Intel EV9+ Skylake GPU, nVidia Pascal) while CPU support is still limited to SIMD conversion only (FP16C). It has been added to allow mobile … Read more…
