Does the 6258R Make Sense for Intel?

For this test, I wanted to compare the difference between Intel’s Xeon Platinum 8280 and Intel’s Xeon Gold 6258R. These processors are practically identical on paper for any regular 1P or 2P server, offering up 28 cores at 2.7-4.0 GHz, however the Gold 6258R has a list price that saves over $6000 compared to the Platinum 8280.

As per our regular testing procedure, I put both CPUs in our 1P LGA3647 test system and ran through our performance benchmarks. We also took power measurements, latency measurements, and idle-to-turbo measurements. Everything came out the same. Without the name of the CPU on the heatspreader, or a different CPU string when probed, no-one would be able to tell the difference in a 1P or 2P environment.

So if anyone is thinking of deploying Intel’s high-end Xeon Platinum 8280s in anything less than a eight-socket system, don’t bother. Save a few grand per CPU and gain the plaudits of your boss – unless they start asking questions about why the infrastructure doesn’t have the latest ‘Xeon Plutonium’ things they’re heard about.

Jokes aside, the pragmatic question to ask is:

Has Intel shot itself in the foot with the 6258R?

Intel often repeats (as does AMD) that the majority of its server customers exist in that 1P and 2P spectrum. An offering like the 6258R replaces the 8280 in all aspects for that, giving Intel an effective performance-per-dollar improvement of 2.5x, while at the same time lowering its selling price - when we compare the prices, Intel stands to lose $6000 per processor sold.

 

However, Intel launched the 8280 in April 2019 as the flagship – the 6258R only came out in February 2020. Anyone who wanted the perfromance of the 8280 in that time frame already purchased one. At the same time, a few months later, the company has launched its 3rd Generation Xeon Scalable platform, known as Cooper Lake. We’ve covered Cooper Lake in detail, but the short information is that it is an OEM platform designed for 4-socket and 8-socket servers. Any customer who needs servers that large are now going to look at Cooper Lake as the leading product, meanwhile the 1-socket and 2-socket customers are still on the Cascade Refresh options.

At this point, the 8280 is a dead product for Intel.

  • Users who want the 4-8 socket compatibility and performance can now get the 8380H/HL.
  • Users who want the 1-2 socket compatibility and performance will go for the 6258R.

If you’re wondering where the 6258R stacks up against AMD, we’re in the process of re-testing the parts we have on hand as we go through our regression testing. The EPYC 7542 is probably the best comparison point (32C, 2.9-3.4 GHz, 225W, $3400), however we’ll have to look into getting one of those.

    You’d also think people would read the whole article before making such remarks. From the article:

    This isn't new from Intel: in the past, they've always charged double for the largest officially-supported socket-count bump.

    But since they started offering more than 4 sockets, the jump between the two has gotten ludicrous. But yes, always a good idea to check your required socket count before you jump in.

    And the fact that there is that other company now offering competitive products. Hmm... what was it called again? I looked at the second page of the article for benchmarks but didn’t find any.

    Now I see your issue. There’s three pages, not two. The answer you seek is on the third page.

    Oxford might want to file an injunction against his name. If successful he will just be known as, Guy.

    Raise a new question: single server with 8 socketed 8280 vs 4 server clustered 2 socketed 6258R.
    Performance / price wise total cost and performance/wattage consumption.

    Why Don't migrate to AMD Epyc Platform that has Octa channel in the full stack of products from 8core Cpu to 64Core cpu

    I think you're missing that the 6258R is 2UPI vs 3UPI on the Platinum SKU https://ark.intel.com/content/www/us/en/ark/compar...

    How many 2S motherboards actually wire up all three UPI links between two sockets? I've seen at least one Intel slide indicating it's a supported configuration, but most diagrams seem to show just two UPI links in use for 2S boards.

    "were designed to *bolder up* Intel’s server offerings"

    Did you mean "bolster"?
