Thinking of getting a new cpu but undecided between:

AMD Athlon 64 X2 Dual Core 4800+

AMD Opteron UP 175 Dual Core San Diego 2.2GHz 2MB Cache

What's the difference between the two?

I hear lots of people talking about the Opteron's.

I'm a keen gamer and want to know what chip would be the best choice upgrading from a 4000+ San Diego?

Cheers.
 
The 175 is a chip meant for a server so it'll be a little bit more stable. Effectively it means you'll most likely get higher overclocks with it. Make sure you've got a decent motherboard though.

:edit: whoops forgot to mention. The 4800+ is cloekd at 2.4ghz with 1mb cache while the opteron is 2.2ghz with 2mb cache. SInce you'll be able to clock the flak out of the oppy, the speed difference is of minimal importance. It's cheaper too!!!!!

The 4800+ has 2mb cache, same as the opty. The only difference is the 12 multi on the 4800+ and the 11 on the opty. Doubt either will go much over 2.8Ghz, get the 170 and save your money.

AMD Opteron UP 175 (£387.69 inc VAT)
Application: Server
Clock Speed: 2.2Ghz (11 x 200Mhz)
L2 Cache: 1MB per core (combined total of 2MB)
Stock Volts: 1.3V - 1.35V

AMD Athlon 64 X2 4800+ (£458.19 inc VAT)
Application: Desktop
Clock Speed: 2.4Ghz (12 x 200Mhz)
L2 Cache: 1MB per core (combined total of 2MB)

That's the technical difference between the two. I would take the Opteron without a shadow of doubt.

OcUK is advertising them with half cache then, or maybe I'm just a spacker.

lol, a lot of people seem to be confused about the "2MB cache" advertising on OcUK's Opterons. It is misleading, and somewhat sly.

Both the X2s and Opterons have 1MB L2 cache per core, multiplied by two cores which gives a total of 2MB. The Opterons are advertised at the total cache of both cores combined (i.e. 1MB + 1MB = 2MB), whereas X2s are advertised at the amount of cache each core has (i.e. 1MB).

So, there's really no difference in the amount of cache. The only difference is the advertising technique (which leads to confusion).
