Intel Xeon quad Socket Benchmarks (SAP)

A quick look at Intel quad socket quad core
Check out the benchmarks at

So Sum up.
HP ProLiant DL580 G5, 4 processors / 16 cores / 16 threads, Quad-Core Intel Xeon Processor X7350 2.93 GHz, 64 KB L1 cache per core and 4 MB L2 cache per 2 cores

Score = 18530

To compare against a dual Socket

HP ProLiant DL380 G5, 2 processors / 8 cores / 8 threads, Quad-Core Intel Xeon Processor X5365 3 GHz, 64 KB L1 cache per core and 4 MB L2 cache per 2 cores

Score = 10430

Scaling

A 4 way intel at 2.93 gives a score of 18530 so at 3GHz that would be
18973 to going from 2 way to 4 way at the same frequency = 81 % improvement in doubling of cores

So compare with AMD Opteron Quad socket

HP ProLiant BL685c, 4 processors / 8 cores / 8 threads, AMD Opteron Processor Model 8222 3 GHz, 128 KB L1 cache and 1 MB L2 cache per core

Score = 10530

Compared to AMD dual socket

HP ProLiant DL365, 2 processors / 4 cores / 4 threads, AMD Opteron Processor Model 2220 2.8 GHz, 128 KB L1 cache and 1 MB L2 cache per core

Score = 5430

Current Opteron is just a little faster for the same number of cores at the same frequency.

Scaling for Opteron

5430 was at 2.8 GHz to at 3GHz that would roughly be 5817
So Scaling is roughly 81% again.

What will that mean for Barcelona? If the performance of Barcelona were the same as Opteron but with quad cores at the same 81% scaling (although in truth scaling tends to go down though with number of CPUs) then Barcelona would just pull ahead.
If Barcelona is 20% faster than Opteron (at the same clock) then in this server benchmark Barcelona should be nicely ahead.
So AMD will need to get to 2.4GHz to match the current Intel chips in this benchmark. However AMD does have another ace up it's sleeve. 8 Sockets, I believe SUN already have an 8 Socket board that work with Opteron

  1. Interesting dissection of the numbers. Intel hasn't typically scaled that well, so that's encouraging - looks like Tigerton is going to put the pressure on Barcy to have to succeed, just long enough for Penryn to jump in and take the lead back. Yes, I'm assuming that Barcelona will beat the Caneland platform and I'm assuming that Penryn's as good as we've heard (I figure those are equally lofty claims, since we've seen the same amount of independent benchmarks for both :-D).

    I dont believe the first Barcelona is meant for the 4P market. 2P only I think. Apples to oranges comparison comparing tigerton to barcelona. Barcelona competes more with Clovertown.

    Also, you can't extrapolate 4 cores -> 8 cores and get 16 cores. The scaling is tricky. Scaling is worse going from 8 cores -> 16 cores vs 4 cores -> 8 cores.
  3. Here's some more performance numbers as well.

    I haven't had the opportunity to disect the numbers yet though...will have to look closer tonight.
