Intel's server CPU portfolio just got more diversified and complex with the launch of the Intel Xeon E3-1200 V4 at Computex 2015.  It is basically the same chip as the Core i7 "Broadwell" desktop that Ian reviewed yesterday: inside we find four Broadwell cores and a Crystal Well-backed Iris Pro GPU, baked with Intel's state-of-the-art 14 nm process. The Xeon enables ECC RAM support, PCI-passthrough, and VT-D, the former two being features that the desktop chips obviously lack, and VT-D only being present in some desktop chips.

But the current line-up of the Xeon E3-1200 v4 based upon Broadwell is not a simple replacement for the current Xeon E3 1200 v3 "Haswell", which we tested a few months ago. Traditionally, the Xeon E3 was about either workstations or all kinds of low-end servers. 

It looks like the current Xeon E3-1200 v4 is somewhat a niche product. Besides being a chip for workstations with moderate graphics power, Intel clearly positions the chip as a video transcoding and VDI platform. It looks like - once again - Intel is delivering what AMD promised a long time ago. AMD's Berlin, a quad steamroller with Radeon GPU was supposed to address this market, but the product did not seem to convince the OEMs.

Intel claims that the 65W TDP E3-1285L v4 was able to decode 14 1080p (at 30 fps) 20Mbps streams, four or 40% more than on the Xeon E3-1286L v3, which could only sustain 10 video streams. Another use are virtual desktops that use PCI device passthrough to give the virtual machine (VM) full access to the GPU. That way of working is very attractive for an IT manager: it enables centralized management of graphical workstation in a secure datacenter.  

But it is should be noted that this kind of virtualization technology comes with drawbacks. First of all, there is only one VM that gets access to the GPU: one VM literally owns the GPU (unlike NVIDIA's GRID technology). Secondly you add network latency, something that many graphical designers will not like as adds lag compared to the situation where they are working on a workstation with a beefy OpenGL card. 

Below you can find the table of the 5 new SKUs. I added a sixth column with the Xeon-D, so you can easily compare.

L4 Cache none 128MB (Crystal Well) 128MB (Crystal Well) 128MB (Crystal Well) 128MB (Crystal Well) none

It is pretty clear that the Xeon-D is a much more attractive server chip for most purposes: twice the amount of cores, twice the amount L3-cache, while remaining inside a 45W TDP power envelop. On top of that, the new Xeon E3 v4 still needs a separate C226 chipset and is limited to 32 GB of RAM. The Xeon-D does not need a separate chipset and supports up to 128 GB of DDR-4. 

In summary, the current Xeon E3-1200 v4 lineup is only interesting if you need a server chip for video transcoding, centralized workstation or a local workstation with relatively modest graphical needs. 

The Atom C2000 and hopefully the X-Gene 2 chips are the SoCs to watch if you want ultra dense and relatively cheap server cpus for basic server processing tasks (static web content, object caching). The Xeon E3-1240Lv3 is probably still the best "single/lowly threaded performance"/watt champion. And the Xeon-D? Well, we will be reviewing that one soon...

    The Xeon E3's all have the graphics lithography on-die, it's just deactivated. For example, the die of the E3-1230v3 is identical to a i7-4770.

    The i7-4770(k) has an enabled IGP and overclocking support.
    The E3-1230v3 has disabled graphics and ECC support when combined with a capable chipset. Obviously if you run one in an 80/90 series chipset there is no ECC support but the chip otherwise matches the performance for $100 less.

    Dont worry guys, the Broadwell gen is a bit screwy. I think things will be much more "back to normal" with skylake stuff. Soon. Reply

    They were never good gaming chips. An i5 clocked higher was better in 95% of games and cheaper. People buying E3s as gaming chips was an extremely niche market. Reply

    I bought the 1230 v3 in 2013 hoping games would get better at multithreading thanks to new consoles. That has not happened yet, but it still might with DX12.
    Still, 3.5 GHz is fine in most games, and HT is useful when I do video encoding.

    Same reason why I got a 3930K. Thankfully at 4.8ghz it will still give Haswell-E a run for it's money.
    The 6 cores/12 threads seemed like a good idea at the time for longevity, my Q6600 is still running games today despite multiple people recommending against picking up that chip due to the lack of software/games that could use those cores.

    Well... Guess who got the last laugh? :P
    I expect a similar thing with my 3930K, it's been 4 years and it still handles everything you could throw at it.

    Have you played witcher 3? If you need higher fps (60+), something with HT (4770, xeon e3) is the way to go, as it adds some 20% compared to 4670 at the same power consumption level and without the need for a big cooler and overclocking Reply

    I have a haswell E3, and I bought it for a small home server.
    Why do you think they're popular for gaming PCs. They're very similarly priced to the equivalent i5/i7.

    How is the E3-1285 v4 in any way better than the E3-1285L v4? The latter costs less, has a higher base frequency, and a lower TDP. Or am I missing something?

    Also, an "E5" slipped through in one paragraph where I think you meant "E3".

    same thing i was wondering... Reply

    I think the table must be wrong. The Model and TDP got swapped. The E3-1285 v4 makes sense as the E3-1285L v4 if you assume it should be 65w instead of 95w. Slightly slower base speed and higher price. Going the other way Higher base speed and 95w but slightly cheaper. Fits the way intel usually does the low power processor. Reply
