Therefore the maximum GFLOPS is 32*68*1.4 = 3046.4 DP GFLOPS. For a single core the peak FLOPS is 32*1.6 = 51.2 DP GLOPS. Dense matrix multiplication is one of the few operations that actually is capable of getting close to the peak flops. The Intel MKL library provides optimized dense matrix multiplication functions. On a Sandy Bridge systems ... Take, for example, the Intel Xeon E5-2680 "Sandy Bridge" processors in Stampede where I work. The specs are: 2.7GHz; 2 chips/node, 8 cores/chip; 2 vector instructions/cycle ; 256-bit wide AVX instructions (4 simultaneous double-precision operands) Multiplying those gives 345.6 GF/node or 2.2 PF for the un-accelerated part of the system. We usually think in terms of double-precision (64-bit ... I'm confused on how many flops per cycle per core can be done with Sandy-Bridge and Haswell. As I understand it with SSE it should be 4 flops per cycle per core for SSE and 8 flops per cycle per core for AVX/AVX2. This seems to be verified here, How do I achieve the theoretical maximum of 4 FLOPs per cycle?,and here, Sandy-Bridge CPU specification. Take, for example, the Intel Xeon E5-2680 Sandy Bridge processors in Stampede where I work. The specs are: 2.7GHz; 2 chips/node, 8 cores/chip; 2 vector instructions/cycle; 256-bit wide AV...

So i finally got up to 5.0GHz!!! Not sure why but my Cinebench score is lower than when iwas at 4.8GHz. I was having troubles loading the program so i loaded the 32 bit version instead of 64. Not ... In this video I'm going to be benchmarking my Xeon E5-2650 rig, replacing that Xeon with an E5-2670 (showing the process involved while changing the CPUs), benchmarking it and putting both these ... The core i7 2600 is too expensive, the core i7 2600s is too expensive, so that got me thinking - why not use a Sandy Bridge era Xeon that fits in the same so... #SandyBridge, #IntelCPUs, #CoffeeLake Sandy Bridge is an Intel CPU microarchitecture which debuted in late 2010 and quickly became a landmark in performance ...
