Intel Core i7 6700K: Test Skylake, new bomb?

Corsair Air Series in Carbide 300R To test the performance of Skylake, we used a variety of platforms:
  • Motherboard Asus Z170 Deluxe (BIOS 5504)
  • 2x 8GB Corsair DDR4-2666 memory @ 2666MHz,
  • Samsung SSD 256GB 840 Pro
  • 980 graphics card Gigabyte G1 Gaming
  • Power Cooler Master V1200 Platinum
  • Corsair H105 Cooling
New socket requires, the LGA-1151 platform we used to test the only processor Skylake of our selection: the Core i7 6700K. We will obviously confront the Core i7 Haswell and Broadwell, on the following platform:
  • Motherboard ASUS Z97-Deluxe (BIOS 2501)
  • 2x 4GB Corsair DDR3-2133 memory @ 1600MHz,
  • Samsung SSD 256GB 840 Pro
  • 980 graphics card Gigabyte G1 Gaming
  • Power Cooler Master V1200 Platinum
  • Corsair H105 Cooling
On this platform, we test the Core i7 4770K, Core i7 4790K, but the Core i5 and Core i7 5675C 5775C, two generation Broadwell processors. We also oppose all this small world to Core i7 Extreme processors via the platform:
  • Motherboard Asus X99-Pro (BIOS 1801),
  • 2x 8GB Corsair DDR4-2133 memory @ 2133MHz,
  • Samsung SSD 256GB 840 Pro
  • 980 graphics card Gigabyte G1 Gaming
  • Power Cooler Master V1200 Platinum
  • Corsair H105 Cooling
On this system we test the Core i7 5820K and 5960X. Finally we included an AMD configuration to oppose the Intel processors, offer AMD:
  • Motherboard Asus Crosshair V (1703 BIOS)
  • 2x 4GB Corsair DDR3-1866 memory @ 18661MHz,
  • Samsung SSD 256GB 840 Pro
  • 980 graphics card Gigabyte G1 Gaming
  • Power Cooler Master V1200 Platinum
  • AMD reference air cooling
On this configuration we tested the FX 8350, one of the most powerful AMD processors. All our tests are conducted under Windows 10 Professional Edition x64 with the latest updates available at the time of the test. We use the NVIDIA 353.62 drivers.

3DMark - Tek Extreme


Skylake - 3DMark
In 3DMark here executed in 2560 x 1440, this is the graphics card that limit our performance ... on all platforms. The results are very close and surprisingly, the leading duo consists of the Core i7 5820K and the FX 8350 AMD. Difficult in any case to learn from this specific test.

PCMark 8 - Creative - accelerated


Skylake - PCMark 8
We use the capricious PCMark 8 with the creative test performed by activating the OpenCL acceleration. Skylake dominated by debates with performance 5% higher than the Core i7 4790K and 8% higher than the Core i7 4770K. The 8350 FX AMD closes the march here while Core Broadwell fail to reach the level of the Core i7 5820K.

Sandra 2015 - CPU


Skylake - Sandra 2015 - CPU
The test Sandra processor evaluates the number of operations that can run our systems to second. In this game, the more the number of cores increases, the processors are swift. Thus the Core i7 5960X and 5820K are leading. Skylake came in third with a score more or less lead over Haswell depending on whether one considers the GIPS Glops or results.

Sandra 2015 - Memory


Skylake - Sandra 2015 - Memory
Sandra memory test gives preference to Core i7 5960X and 5820K the only beneficiaries of a quad-core i7 6700K channel.The architecture is third with a significantly higher memory bandwidth to Haswell processors: going from 18 Gb / s 26 GB / s on average!

ScienceMark 2.0 x64 - Primordia


Skylake - ScienceMark 2.0
Synthetic in nature and rather old, ScienceMark 2.0 gives preference to Core i7 5775C. This is a Broadwell chip that yet should be back from his counterparts. With a frequency stock 3.3 GHz and 3.7 GHz Turbo should not even tickle the Core i7 4790K and 4.4 GHz Turbo. It remains also led Skylake face. Yes, but remember that Broadwell chips have a little something extra that is not related to the frequency: the embedded eDRAM, still 128 MB, which can be decisive; this is the case here. Skylake meanwhile boasts performance 7% higher than the Core i7 4770K and 21% higher than the Core i7 5960X, which "is expensive" here.

Fritz Chess Benchmark


Skylake - Fritz
Fritz calculates the effectiveness of our processors in simulation chess. The result is expressed in kilonoeuds per second and careful, Fritz can handle more than 8 threads, a limit for our Core i7 5820K and 5960X. The Core i7 6700K dominates here much debate followed the Core i7 4790K. Facing the Core i7 4770K, the performance gain is 18%. A gap that reached 31% compared to a i7 5960X and 32% against the AMD 8350 FX. The red lantern here is the Core i5 5675C, penalized by the lack of HyperThreading. < Previous page Next page > Edited on 04/12/2016 at 9:56
