Intel Haswell-EP Xeon E5-2699 v3 Benchmarks; Mediocre Overclocking

In my earlier report I revealed a few benchmarks of the upcoming Intel Haswell-EP Xeon E5 2699 v3 processor. Today, a user at Coolaler Forums got hold of several E5-2699 v3 chips and put them to test using Cinebench R11.5 and also showed off the CPU’s overclocking capacity. Unfortunately, the user did not reveal the complete test bed including which motherboard and memory he used in his Xeon E5-2699 v3 benchmarks. Anyways, we do have initial performance numbers to judge the CPU’s performance till more comprehensive test results are revealed.

Intel Haswell-EP Xeon E5-2699 v3 benchmarks and overclocking results

Before we move on to the analyse the performance of Xeon E5-2699 v3, lets assume the test bed because the user used for his testing. In the image, we can spot two DDR4 modules which resemble Avexir’s Platinum DDR4 memory which was revealed earlier. As for the motherboard, it’s definitely a X99 motherboard because a single CPU was tested and we haven’t spotted any C610 chipset motherboards yet. Intel Haswell-EP Xeon CPUs are only compatible with LGA 2011-3 socket and Intel C610 and X99 chipsets.

Xeon E5-2699 v3 features 18 cores and 36 threads clocked at 2.3 GHz. In the benchmarks, the processor is overclocked to 2.8 GHz and 2.9 GHz so a performance jump is expected compared to stock clocks. As you can see in the screenshot above, the initial 2.8 GHz speed can be achieved by increasing the CPU multiplier to 28 (also acting as Turbo Boost). For another 100 MHz, some old BCLK overclocking is required and an increase of 5 MHz in the BCLK results in 2.9 GHz CPU speed.

It seems like Cinebench R11.5 does not fully supports the latest Xeon E5-2600 v3 line up because the screenshot shows that CPU load is only 88% instead of 100%. Anyways, with 18 cores and 36 threads running under the hood I doubt any application will dare to have hiccup.

I had my doubts about the compatibility of the benchmark software and they are getting stronger because in the previous Xeon E5-2699 v3 benchmarks result the CPU scored 25.82 points at stock clocks while the overclocked version in these results scores 24.63 points. The CPU bottleneck is highly unlikely so the only alternate theory remains is the throttling due to high temperature.

The screenshot above reveals the processor running at 2.94 GHz and still not being utilized to its full potential by Cinebench R11.5. With a slight increase in the CPU frequency, the CPU managed 25.98 points in Cinebnech R11.5. Judging by these early results, E5-2699 v3 certainly packs a punch but is it a worthy upgrade from the Ivy Bridge-EP? Only time will tell.

Intel Haswell-EP Xeon processors are expected to launch in the first week of September so hit back and relax because the time is near. For complete details of the line up head over to our exclusive leak.
