Multi-Threaded Integer Performance
Next we run the same workload in several active instances to see how well the different CPUs scale. The Xeon E5 and Xeon D should finally be able to show off their higher core counts.
The Xeon D scales well: performance is multiplied by 8. It is interesting to note that it delivers 82% of the raw integer processing power of the low power Xeon E5, which has 50% more cores and a 44% higher TDP (65W).
We did not test the Xeon E3-1265L v3 (45 W), but the 3.1 GHz chip will end up between the E3-1265L v2 and E3-1240 v3 (3.4 GHz), it will probably score something like 19000. The Xeon D delivers thus no less than 50% more raw processing power at the same TDP, while integrating more functionality. This should further drive down the total power a server uses. This really shows what an excellent improvement the Xeon D is if you can use the 16 threads.
The decompression benchmark tell us the same story as the compression test: the Xeon D delivers.

Thanks for the reply, man.And sorry for my late reply, totally forgot about this thread :)

Nice... Xeon D-1540 is awesome, but I wish it was clocked 0.2Ghz higher across the board would be just enough to tip that scale versus E5. Did my own benchmarks at https://community.centminmod.com/threads/2864/ :)extide - Wednesday, June 24, 2015 - link
Thats probably exactly why it ISNT clocked 0.2Ghz higher across the board ;)I'm sure Intel wants to see some space between this and E5.

If this was marketed for the consumer market with the ability to overclock, this would outsell everything completely. This is what the enthusiast needs!!!Refuge - Tuesday, June 23, 2015 - link
I don't think this is going to do much of anything for an enthusiast.Unless they are interested in building a server for some experiment or project.

I still think the i7 59xx series is a better match for consumers: higher clocks and thus ST performance. The Xeon D most interesting features such as integrated 10 GBe and low power don't interest most performance consumers. Most people will have a hard time saturating a 1 GBe line and power savings are not a priority.tspacie - Wednesday, June 24, 2015 - link
Seems to tick all the boxes for a software development machine. Very good at compilation. Reasonably priced for the performance. Low power. ECC memory. I'm temptedextide - Wednesday, June 24, 2015 - link
EXACTLY what I was thinking!MrSpadge - Saturday, June 27, 2015 - link
I would be very tempted by such a chip as well, using it for BOINC. However, Broadwell looses some of the power efficiency advantage if you push it harder, i.e. the largest gains are at low and moderate frequency. Perfect for such server chips and mobile ones, but not so much for people aiming for 4+ GHz.MaxKreimerman - Tuesday, June 23, 2015 - link
Sounds impresive in just 45w package, but imposible to find in the retail sites such as newegg or wiredzone
