Intel Skylake processors will be unique in several aspects – introduction of a new microarchitecture, Intel 100 series chipset, and will also be able to support DDR3L and DDR4 memory. Will the introduction of new Memory will bring measurable increase in performance?

Intel Core i5-6400T Skylake Performance Comparison With DDR3L And DDR4 RAMs

ECS motherboards H110-Q170-SF100 and SF100 are structurally very similar

One of the Chinese editors decided to check it out on the example of the model Core i5-6400T – featuring four cores clocked at 2.2 GHz (2.8 GHz in Turbo mode), 6 MB L3 cache and just 2-channel memory support DDR3L-1600 + DDR4-2133. In terms of graphics processor integrated HD Graphics (GT2) with 48 execution units. The TDP of processor is estimated at only 35W.

The CPU performance tested on two configurations: the motherboard ECS H110-SF100 and 2x 4GB DDR3L 2133MHz CL11, as well as the motherboard ECS Q170-SF100 and 2x 16GB DDR4 2400 MHz CL17. In both systems there is Plextor SSD M6e M.2 socket. A configuration of this charge with a load of about 40 W.

Before comparing the results, you should still pay attention to the same motherboards (they are structurally very similar). Boards have the format of Mini-ITX and have been designed for industrial applications.

In the Cinebench R15 benchmark platform with DDR3L memory modules generated net 417 cb in the CPU test and 36.69 fps in the OpenGL test, but with memories DDR4 415 cb result in the CPU and 37.33 fps in the OpenGL test. In both cases, the difference margin is even less than 1%.

In 3DMark 11 the difference is also practically negligible – a platform with DDR3L memory received an overall score 2,548 points, DDR4 with memory system scored 2,582 points. Again minor difference.

At the end there is embedded test of the game Resident Evil HD – here the difference is already noticeable, because the average frame rates with older Memory is 58.5 fps and 63.2 fps with DDR4.

So it appears that DDR4 memory will bring a very minor increase in terms of performance. Despite all interest and you will have to buy memory, because manufacturers will be more willing to put on a new standard for – according to our information, the DDR4 memory will be used in the vast majority of motherboards under the LGA 1151 socket (cheaper models will only support the older standard).
