Phenom x4 9850 black VS Athlon II x4 635

I assembled a new rig for a dude whose old machine lost its mobo to a PSU failure. I got a Phenom x4 processor and 8GB of DDR2 for the help. I really wish I would have taken a pic, because it was a really clean build and people were drooling.

I have an Athlon II x4 635 I pulled out of a machine I sold.

I have an AsRock A780GXE/128M. this motherboard only supports DDR2 memory, but will support AM2+ and AM3 processors.

I'm thinking about installing one of these two processors on the AsRock mobo and selling the other. The Athlon II x4 has a higher clock speed, and it is AM3, but does that mean it is better? The Phenom x4 has more cache. Both processors have 512KB per core, but the Phenom has an additional 2MB of L3 Cache.

Besides that, the Phenom can only run DDR2 memory, and the Athlon II can go on a newer board, down the road and run DDR3.

I dislike the lower cache levels, and haven preferred more cache to higher clock speed. Am I prioritising CPU features correctly?

The Athlon II is going to be faster across the board. The early Phenoms are pretty much junk compared to the later chips, and were very limited in clockrate and memory. I recently used a machine that was running a Phenom X4 9950 overclocked to 3.0GHz, and it faired alright, but even a Core 2 Duo or a modern Pentium ran circles around it.

Thanks for the information. I wonder if my E7400 is better.

E7400 would about match the Athlon II per core, but runs out of cores to compete with giving the Athlon II better performance overall in multi-threading.

Gaming wise the Athlon II holds above the E7400 in pretty much everything.

These show an E7500, which is obviously just a little faster than the E7400 so you can deduce the performance from that. The benchmarks are obviously old, but the performance numbers still hold true.

I guess I'm selling the Phenom x4 9850. I'll post it on eBay is a little bit. If you're interested, or know anyone who might, let me know and I'll send pics.
