AMD Ryzen+ 2700X, 2600 Review & Benchmarks – CPU 8-core/16-thread 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 Core i9 7900X (SKL-X) Review & Benchmarks – 4-channel @ 3200Mt/s Cache & Memory Performance

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…

Intel Core i9 7900X (SKL-X) Review & Benchmarks – CPU 10-core/20-thread AVX512 Performance

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: Server 2S, 4S and 8S … 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…

Intel Graphics GPGPU Performance

Intel Logo

Why test GPGPU performance Intel Core Graphics? Laptops (and tablets) are still in fashion with desktops largely left to PC game enthusiasts and workstations for big compute workloads; most laptops (and all tablets) make due with integrated graphics with few dedicated graphics options mainly for mobile PC gamers. As a … Read more…

AMD Ryzen 1700X Review & Benchmarks – 2-channel DDR4 Cache & Memory Performance

What is “Ryzen”? “Ryzen” (code-name ZP aka “Zeppelin”) is the latest generation CPU from AMD (2017) replacing the previous “Vishera”/”Bulldozer” designs for desktop and server platforms. An APU version with an integrated (GP)GPU will be launched later (Ryzen2) and likely include a few improvements as well. This is the “make … Read more…

AMD A4 “Mullins” APU CPU: Time does not stand still…

AMD Logo

What is “Mullins”? “Mullins” (ML) is the next generation A4 “APU” SoC from AMD (v2 2015) replacing the current A4 “Kaveri” (KV) SoC which was AMD’s major foray into tablets/netbooks replacing the older “Brazos” E-Series APUs. While still at a default 15W TDP, it can be “powered down” for lower … Read more…
