AMD Unveils 'EPYC' Server CPUs, Ryzen Mobile, Threadripper CPU and Radeon Vega Frontier Edition GPU (hothardware.com)
MojoKid writes: Today, at its financial analyst day, AMD lifted the veil on a number of new products based on the company's Zen CPU architecture and next generation Vega GPU architecture. AMD CEO Lisa Su lifted a very large server chip in the air that the company now has branded EPYC. AMD is going for the jugular when it comes to comparisons with Intel's Xeon family, providing up to 128 PCI Express 3.0 lanes, which Su says "allows you to connect more GPUs directly to the CPU than any other solution in the industry." EPYC currently scales to 32 cores/64 threads per socket and supports up to 8-channel DDR4 memory (16 DIMMs per CPU, up to 4TB total memory support). AMD also confirmed the previously rumored Threadripper CPU, a 16-core/32-thread beast of a chip for the enthusiast desktop PC space. AMD's Raja Koduri, Senior Vice President and Chief Architect for Radeon Technologies Group, also unveiled Radeon Vega Frontier Edition, a workstation and pro graphics card targeted at VR content creation, visualization and machine learning. Radeon Vega Frontier Edition offers 13 TFLOPS of FP32 throughput, 25 TFLOPS of FP16 performance and is powered by 64 computer units and 16GB of HMB2 memory for about 480GB/sec of memory bandwidth. The cards are expected to ship in June but there was no word just yet on when consumer versions of Vega will hit. Finally, AMD also shared info on Ryzen Mobile, which will incorporate both the Zen CPU architecture and an integrated Vega GPU core. Compared to AMD's 7th generation APUs, AMD claims Ryzen Mobile will up CPU performance by 50 percent while offering 40 percent better graphics performance. AMD also claimed those gains will not come at the expense of battery life, with a 50 percent reduction in power consumption, which reportedly will pave the way for faster, longer lasting premium notebooks and 2-in-1 devices.
Once Threadripper is out, AMD will have a consumer chip with more cores than Intel's top enthusiast chip. Intel's enthusiast chip with the most cores was the ($1600) 6950X with 10 cores, and a 12-core Skylake-X upgrade is expected to release in a few weeks. The big question is pricing on these chips. Once the hype dies down, the question is who really needs these? Professionals who REALLY need to quickly reencode lots of video at maximum quality, or run lots of Photoshop filters, can afford a $1600 chip. That $300 Ryzen with 8 cores will be 'good enough' for nearly everyone who can't afford to spend top dollar, otherwise you should use the EPYC, or the Radeon Vega Frontier Edition.
I hear that most servers only user 4-core CPUs and don't need more than that, so I guess EPYC will be a niche use-case.
