Intel Xeon E3-1575M v5
The Intel Xeon E3-1575M v5 is a fast quad-core processor for workstation notebooks based on the Skylake architecture and was announced in the beginning of 2016. It was the fastest chip of its series at the time of the launch. Besides four CPU cores incl. Hyperthreading support, which are clocked at 3.0-3.9 GHz (probable Turbo steps: 4 cores: up to 3.5 GHz, 2 cores: up to 3.7 GHz), the processor also integrates a very fast graphics unit. The Iris Pro Graphics P580 (GT4e) has 72 EUs as well as 128 MB eDRAM cache, which can also be used by the CPU cores. It is manufactured in a 14 nm process with FinFET transistors. The most important difference to the consumer models like the Core i7-6920HQ is the support of additional administration and security features like support for ECC-RAM.
Intel uses Skylake to replace both Broadwell as well as Haswell and therefore uses one core design for all TDP classes between 4.5-45 Watts. Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.
The Xeon E3-1575M v5 also benefits from the additional eDRAM cache in some cases, which can accelerate memory-heavy applications in particular.
Thanks to the improved Skylake architecture as well as the additional eDRAM cache, the E3-1575M v5 should even beat the former top model Core i7-4940MX (Haswell) and is therefore one of the fastest notebook processors on the market right now. Even the most demanding applications and excessive multi-tasking are no problem for the high-end CPU.
The integrated GPU with the designation Iris Pro Graphics P580 (also known as "GT4e") represents the fastest version of the Skylake GPU (Intel Gen. 9). 72 Execution Units (EUs) run at 350 up to 1100 MHz and allow a performance comparable to a dedicated mainstream chip. The GPU might be able to compete with a GeForce 945M under perfect conditions and it is therefore the fastest iGPU on the market by a pretty big margin. Modern games from 2015/2016 can usually be played smoothly at medium settings. More information about the performance and the features is available on our dedicated page for the Iris Pro Graphics P580.
According to its TDP of 45 Watts, the chip is primarily designed for bigger notebooks starting with 15-inch screens. The TDP can optionally be reduced to 35 Watts (cTDP down), but this would obviously affect the performance.
