Intel Broadwell-EP Xeon E5 v4 Because Why Not?

Intel has made its way on to our news feed several times over the last few days. The ticking and the tocking seem to be back on schedule. Was Intel held back by the complexity of 14nm? Was it too difficult for them to focus on both high-performance and mobile development? Was it a mix of both?

VR-Zone, who knows how to get a hold of Intel slides, just leaked details about Broadwell-EP. This product line is predicted to replace Haswell-EP at some point in the summer of 2015 (they expect right around Intel Developer Forum). They claim it will be Intel's first 14nm Xeon processor which obviously suggests that it will not be preceded by Broadwell in the lower performance server categories.

Broadwell-EP will have up to 18 cores per socket (Hyper-Threading allows up to 36 threads). Its top level cache, which we assume is L3, will be up to 45MB large. TDPs will be the same as Haswell-EP which range from 70W to 145W for server parts and from 70W to 160W for workstations. The current parts based on Ivy Bridge, as far as I can tell, peak at 150W and 25MB of cache. Intel will apparently allow Haswell and Broadwell to give off a little more heat than their predecessors. This could be a very good sign for performance.

VR-Zone expects that a dual-socket Broadwell-EP Xeon system could support up to 2TB of DDR4 memory. They expect close to 1 TFLOP per socket of double precision FP performance. This meets or exceeds the performance available by Kaveri including its GPU. Sure, the AMD solution will be available over a year earlier and cost a fraction of the multi-thousand-dollar server processor, but it is somewhat ridiculous to think that a CPU has the theoretical performance available to software render the equivalent of Battlefield 4's medium settings without a GPU (if the software was written with said rendering engine, which it is not... of course).

This is obviously two generations off as we have just received the much anticipated Ivy Bridge-E. Still, it is good to see that Intel is keeping themselves moving ahead and developing new top-end performance parts for enthusiasts and high-end servers.

F-ing amazon ad pops up when I am not even hovering of its client area, add KOs my entire post! WTF WTF.

On the posting page, if the composing/process of composing text is not retained on the page after an auto/ad refresh before post completed, then the results after an automatic ad that redirects/causes a refresh on a Mouse hover event, and not the mouse down event, is a recipe for posting disaster. ads on post composing portions of web pages should never trigger refreshes/redirects to ads on the mouse hover event. And ads should not be tracking cursor movements outside the client area of the ad, or triggering/redirecting on mouse hover events outside the client area of the ad.

Not sure what you are referring to here - we only have static banners from Amazon running.  Shouldn't be doing any kind of refreshing, etc.

Nothing dodgy happening with ads at my end, just the usual banners on the most informative and knowledgeable PC website in the business today!

Ads sometimes do things (through no fault of the website creators/owners) with the code/frameworks, be they IE realted, or flash related, or other! This is often the fault of the ad's web based services/content provider and OS/browser/plugin functionality, as it maybe handles HTML/standards in a not so standard way, IE being such a browser with problems, as well as others. Static ad content flags can be corrupted through errors, as well the delegated mouse event handlers in the software stack's object Properties (bad Mouse position coordinates) and faulty code. Flash based ads are a pain in many user's browsing experience, bogged down browser interaction and performence among, the many other problems.

Intel is frantically trying to catch up to AMD ,I doubt they will beat the igp in Richland let alone the one in KAveri
and if it is only on their upper echelon parts then it is next to useless.
Very soon most if not all games will be HSA compliant Intel will have to join the HSA foundation or lag behind.
I am not optimistic I bought an Intel processor last year and it's igp is dismal and the chip overheats too much.
Im about done with Intel.

This is not an iGPU. This is a multi-core CPU (a multi-thousand-dollar one mind you) with, allegedly, higher performance than AMD's APU (a couple-hundred-dollar one) even if you include the theoretical performance of the GPU.

and in the end who really cares about iGPU gaming lol. I don't care how good the iGPU's get for either AMD or Intel, they're still going to suck when it comes to gaming. Laptops and mobile devices it'll be somewhat tolerable, but if they keep focusing on iGPU's something will eventually suffer as we've seen lately with Intel. The CPU portion will be left unattended for years and years.

Really, how big is the data bus, internal and what about the external data bus on this Intel SKU, and the the flops results moved to memory on this server chip, what are the latencys, best case amortization wise, of this chips's IO subsystems moving, say one gigabite into and out of memory from the FPUs, as opposed to the APU's HSA hUMA and internal GPU. The gaming APUs have CPUs that share a much larger GPU sized databus with memory, and faster memory. the Intel is a server chip with a lot of cores and SIMD units, but the ability to perform flops is not the only measure of graphics performence, and this Intel CPU lacks the other specilized units that an APU has, and should never be directly compared to a fundamentally different APU/GPU product, on FLOPS alone! It really is confusing when Flops are thrown out there as a metric, and is never quilifed as being single or double precision. And the Kaveri APU's Flops, is that including the floating point performence of its CPU cores' SIMD flops, along with Its GPUs Flops, or just the GPUs flops. Intel's x86, as well as AMD's, and ARM has SIMD units, so how many Flops can say 18 ARM 64 bit CPU cores perform, and there will be ARM server chips on the market to compare, hopefully with at least 24 ARM cores. I would love to see more comparisons in the future between Apple's Customizied ARM ISA based designs, as well as the other ARM based companies, the use their own custom ARM ISA based designs, as mostly the metrics I am seeing are just the metrics on the ARM refrence designs. AMD will be bringing all the HSA hUMA goodness to its own ARM ISA based ISA designs, as well a Nvidia, through its use of ARM based designs, ARM is also a founding member of the HSA foundation, with AMD and others, so ARM holdings should be introducing ARM refrence designs with HSA and uHMA also, in the future.

You want to know what PR pages all those backlinks are coming from.

One powerful way to get free backlinks and free traffict is
by posting articles on the site - article submission sites.

These three tools can dig up much more backlinks
to a site than any other backlink checkers out there. This is because the goal isn't just to create as many backlinks as
possible rather to have ones generated in the sites that matter.
