Intel Xeon E3-1575M v5 vs Intel Xeon E3-1505M v5

Intel Xeon E3-1575M v5

► remove Intel 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. 

Architecture

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.

Performance

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.

Graphics

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.

Power Consumption

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.

Intel Xeon E3-1505M v5

► remove Intel E3-1505M v5

The Intel Xeon E3-1505M v5 is a high-end quad-core processor for workstation notebooks. It's part of the Skylake Xeon series and has been presented in September 2015. In addition to four CPU cores with Hyper-Threading clocked at 2.8 - 3.7 GHz (4 cores: max. 3.3 GHz, 2 cores: max. 3.5 GHz), the chip also integrates an HD Graphics P530 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The CPU is manufactured using a 14 nm process with FinFET transistors.

The most important difference of the Xeon series compared to consumer models like the Core i7-6920HQ is the support for additional management and security features such as ECC memory.

Architecture

Skylake replaces both Haswell and Broadwell and brings the same microarchitecture in every TDP class from 4.5 to 45 W. The extensive improvements of the Skylake design include increased out-of-order buffers, optimized prefetching and branch prediction as well as additional performance gains through Hyper-Threading. Overall, however, performance per clock has been increased by only 5 to 10 percent (compared to Haswell) respectively under 5 percent (compard to Broadwell), which is quite modest for a new architecture ("Tock").

Performance

Thanks to its improved architecture, the E3-1505M v5 performs somewhat better than most Haswell-based predecessors like the Core i7-4900MQ and is just slightly slower than a Core i7-4770K (desktop). Under long-lasting full load, the Skylake chip profits by its advanced 14 nm process, which leads to a higher energy efficiency and reduces throttling.

Even the most demanding applications and excessive multitasking are handled easily.

Graphics

The integrated graphics unit called HD Graphics P530 represents the "GT2" version of the Skylake GPU (Intel Gen. 9). The 24 Execution Units, also called EUs, are clocked at 350 - 1050 MHz and offer a performance about 20 percent above the old HD Graphics 4600. Games of 2015 can thus be played smoothly in low or medium settings. For more information about performance and features, check our page for the HD Graphics P530.

Power Consumption

Specified at a TDP of 45 W (including CPU, GPU and memory controller), the Xeon is best suited for bigger notebooks 15-inches in size and above. Optionally, the TDP can be lowered to 35 watts (cTDP down), reducing both heat dissipation and performance.
