AMD's Phenom X3 Processors

Sisoft Sandra Synthetic Benchmark Performance

Sisoft Sandra is a great synthetic benchmark suite that allows testing of numerous system components. I’ll be using the CPU arithmetic, Memory Bandwidth and Memory Latency tests.

We’re using version 14.20, which is multi-core aware and triple-core friendly.

As you can see, there is a lot of potential processing power in the X3s. Even the E8400 is outpaced by the X3 8750 in these multi-core tests.

Thanks to the integrated memory controllers, the AMD chips have heaps of memory bandwidth at their disposal. The Phenoms even more so than the X2s.

Intel’s very fast and very large L2 cache really brings down their overall random access latency.

24 Apr 2008 ~ 3:03am Leonardo Thanks for the review, Mike.

Very interesting.
24 Apr 2008 ~ 10:20am GHoosdum It was great that you went the extra mile and cleared the "bad" core issue up with AMD. Go Mike!
24 Apr 2008 ~ 10:42am Winfrey These seem like a decent step up from the "X2" AMD processors. I'd personally like to see how they fold with an SMP client. Pretty encouraging for AMD, it's not beating intel soundly but the fab process definitely helps AMD to keep prices very competitive.

Learned lots thanks Mike!
24 Apr 2008 ~ 10:45am primesuspect Now I want one
24 Apr 2008 ~ 10:58am BuddyJ As do I.
30 Apr 2008 ~ 8:48pm Straight_Man I'll have to wait and see-- can't afford such a machine in the next six months-- but will be interested to see how they spread and how popular they are. I am running a 2.66 GHz Intel processor now that was state of the art 4 years ago, due to the fact that I have no current applications that can use multiple cores in the versions I have.

No, AMD prices are de facto set by Intel. AMD has no choice in the matter.

Correct but the fab process helps take some pressure off of being forced to set that low price, as in it is more affordable for AMD than if they didn't have their fab process.
1 May 2008 ~ 5:18am Your-Amish-Daddy Well. Three cores...I don't really know what to think of that... I remember when two cores meant two physical chips, back in the day of the Athlon MP's and dual P3 Slot rigs...MAN thsoe made powerful machines. But I wonder if XP will handle 3 cores...?
1 May 2008 ~ 6:18am Thrax XP can handle however many cores CPU manufacturers can fit into two physical sockets.
