Scalable CPUs to watch

[funkywizard]

Probably will start seeing scalable coming on the used market in the next year or so.

As you can get 14 core E5-2680v4 CPUs for $150 ea and 18 core E5-2695v4 CPUs as low as $200 each, I think you'll want to see 22 - 24 core scalable CPUs in the $200 range to justify an upgrade. As 28 cores is top end for scalable first gen I doubt those will be affordable anytime soon.

With that premise, here are the CPUs I'll want to keep an eye on:

Specs as per wikipedia: List of Intel Skylake-based Xeon microprocessors - Wikipedia

Xeon Gold 6152 -- 22 cores, 2.8ghz all-cores-turbo, 140w TDP

Xeon Gold 6162 or Xeon Platinum 6162 -- 24 cores, 2.5ghz all-cores-turbo, 150w TDP

Xeon Platinum 8160 -- 24 cores, 2.8ghz all-cores-turbo, 150w TDP

The first of these to sell for under $300 ea will be pretty interesting -- will need to keep my eyes peeled.

From CPUBenchmark.net

E5-2680v4 -- 1,932 single thread, 18,203 total
E5-2695v4 -- 1,922 single thread, 20,096 total

Xeon Gold 6152 --2,155 single thread, 22,291 total
Xeon Gold / Platinum 6162 -- not rated
Xeon Platinum 8160 -- 1,984 single thread, 26,485 total

I'm guessing not being ranked, the 6162 is not very popular. Makes sense, lower clock speed offsets the benefit of the 2 extra cores.

The gold 6152 only benchmarks about 10% above the 2695v4 and 20% above the 2680v4, so, I'd need to see that under $200 to bother with it at all.

The Platinum 8160 gives a solid 30% performance bump from the E5-2695v4, so that'll be the SKU to watch for. If that starts being sold for under $300, it'll be a compelling alternative to used E5v4 servers.

It's already on used market for some time now even for the 2nd gen. I actually suggest to keep an eye on OEM models since they could be way cheaper on the same performance level.

Why not buy an AMD Ryzen 5 3600X ? ~ about $274 - can use ECC, Server boards etc, is 7nm chip.

I have done this, installed it in an Asrock/rack board with ECC - it's fast and reliable, running ESXi 6.7u2

It doesnt have enough cores. Not even close

I see people just recommend AMD in just any situations, don't do that... Zen2 has 2-3 times slower inter-core connection latency, about 50% more memory latency, 40% less IOPS for good enterprise 3.0 drives, less decoder on the front end, generally worse L1/branch-predition hit rate, more idle power(along with loaded power at same frequency if FIVR loss isn't present or considered)and not necessarily cheap for every competing performance level, as 24-core xeon is at the price of 12-core ryzen and 6-core I5 is of half the price that of 5600X in China now.

Just know what use case it is before recommend people to jump ship AMD does have the advantage of the largest cache array we ever seen, and a high bandwidth branch prediction design, but they don't apply everywhere.

Was not aware of latency issues you posted. I am not seeing these issues in real world testing.

Ok so what is the application? I mean newegg.com has these for $274..

AMD 3600X = CPU SCORE 18855 - $274 (Desktop CPU) DDR4 3600
E5-2695v4 = CPU SCORE 20096 - $900 (Server Brand new) - more heat, more power DDR4 2400 (yes its much older)

I'm still finding it hard to beat my trusty old 2678v3 for $85 or less

Hi,

I have a question about the 'Xeon Gold 6162 or Xeon Platinum 6162 -- 24 cores, 2.5ghz all-cores-turbo' CPU's:

Why do they have a gold and a platinum version with the same model number? And is it in essence a gold or platinum cpu? I have been trying to figure out why they are so undesirable..
