Pricing Comparison: AMD versus Intel

We are all hoping that the renewed competition between Intel and AMD results in more bang for the buck. Intel just launched about 50 SKUs, so we made a list of those that will go head-to-head with AMD's already announced EPYC SKUs. On average, the Intel SKUs will priced slightly higher, reflecting the fact that Intel believes buyers are willing to pay a bit more for the vendor with the better track record.

Several trends pop up as we look at the table above. 

First of foremost, those 24-28 core CPUs are a wonder of modern multicore CPU architecture, but you sure have to pay a lot of money for them. This is especially the case for the SKUs that can support 1.5 TB per socket. Of course if you can afford SAP Hana, you can afford $10k CPUs (or so the theory goes).

Still, if we compare the new high-end Skylake-EP SKUs with the previous 22-core Xeon E5-2699 v4 ($4199), paying twice as much for a 28-core chip just because it can be used in 8 socket configuration is bad news for those of us who need a very fast 2 socket system. In fact, it is almost as Intel has no competition: we only get a little more performance for the same price. For example you can get a Xeon 6148 (20 cores at 2.4 GHz, 150W TDP) for $3072, while you had to pay $3228 last generation for a Xeon E5-2698 v4 (20 cores at 2.2 GHz, 135W). The latter had smaller L2-caches but a much larger L3-cache (45 MB vs 27.5 MB). We're still not getting big steps forward on a performance-per-dollar basis, a similar problem we had with the launch of the Xeon E5 v4 last year. 

Hopefully, AMD's EPYC can put some pressure on Intel, if not exceed the 800lb gorilla entirely. AMD typically offers many more cores for the same price. At the high end, AMD offers up to 10 more cores than the similar Xeon: compare the EPYC 7551 with the Intel Xeon 6152.

On the other hand, Intel offers lower TDPs and higher turbo clocks. The 16-core EPYC CPUs in particular seem to have remarkably high TDPs compared to similar Intel SKUs. Those 16-cores look even worse as, despite the lower core count and high TDP, the turbo clock is lower than 3 GHz. 

In a nutshell: looking at the current lineups we want lower prices from Intel, and more attractive mid-range SKUs from AMD. 

AMD EPYC Processors (1P)
  Cores
Threads
Frequency (GHz) TDP Price
EPYC 7551P 32 / 64 2.0 -3.0 180W $2100
EPYC 7401P 24 / 48 2.0-3.0 155W/170W $1075
EPYC 7351P 16 / 32 2.4-2.9 155W/170W $750

Finally, AMD's single-socket SKUs – identified by a P suffix – are by far the most interesting to us and the most dangerous to Intel. It will be interesting to see how well two 12-core Xeon 5118s can compete with one EPYC 7551P. The clocks are similar, but AMD has 8 extra cores, a less complex server board, much more PCIe bandwidth, and a lower TDP.  AMD should have serious cost advantage on paper. We hope to check that in a later review.

    Indeed it is a ridiculous comment, and puts the earlier crying about the older Ubuntu and GCC into context - just an Intel Fanboy.

    In fact Intel's core architecture is older, and GCC has been tweaked a lot for it over the years - a slightly old GCC might not get the best out of Skylake, but it will get a lot. Zen is a new core, and GCC has only recently got optimisations for it.

    I kinda miss Infinity Fabric on my Haswell CPU and it seems to only have on die - so why is that missing on Haswell wehen Ryzen is an exact copy? Reply

    Your actually sound similar to JuanRGA at SA Reply

    @CajunArson The cache hierarchy is radically different between these designs as well as the port arrangement for dispatch. Scheduling on Ryzen is split between execution resources where as Intel favors a unified approach. Reply

    Well, that is something that could be figured out if they (anandtech) had more time with the servers. Remember, they only had a week with the AMD system, and much like many of the games and such, optimizing is a matter of run test, measure, examine results, tweak settings, rinse and repeat. Considering one of the tests took 4 hours to run, having only a week to do this testing means much of the optimization is probably left out.

    They went with a 'generic' set of relative optimizations in the interest of time, and these are the (very interesting) results.

    Benchmarks just need to be run on as level as a field as possible. Intel has controlled the market so long, software leans their way. Who was optimizing for Opteron chips in 2016-17? ;) Reply
  • theeldest - Tuesday, July 11, 2017 - link

    The compiler used isn't meant to be the the most optimized, but instead it's trying to be representative of actual customer workloads.

    Most customer applications in normal datacenters (not google, aws, azure, etc) are running binaries that are many years behind on optimizations.

    So, yes, they can get better performance. But using those optimizations is not representative of the market they're trying to show numbers for.

    That might make a tiny bit of sense if most of the benchmarks run were real-world workloads and not C-Ray or POV-Ray.

    The most real-world benchmark in the whole setup was the database benchmark.

    The one benchmark that favors Intel is the "most real-world"? Absolutely, I want AnandTech to do further testing, but your comments do not sound unbiased. Reply
