What is the difference between these two CPUs?

[Steve]

I have both a Sempron 3300+ (socket A) and an Athlon XP 3200+. As you can see from those links everything seems to be the same, so why does the Sempron have a lower TDP? I'm thinking of putting it in my HTPC to replace the Barton so I can cut down on heat, and power draw after I upgrade the video card.

Bump?

probably the amount of cache. Also, there would be difference in power consumption as well since the one with bigger cache will draw more power.

 

[lyssword]

well the part number is exactly same, they must be the same processor @@ I don't think you'll have lower power consumption.

They both have the same amount of cache. I wonder why they have different TDP.

possibly like the new kentsfield revision? B3->G0. only difference is TDP changed (105W -> 95W).

It may just be repackaging. After all, the Athlon XP line has been discontinued.

Or the die sizes may be different (i.e., 130nm versus 90nm).

 

[Steve]

Die sizes are the same too.

Could be newer (better) transistors in the Sempron.

The Sempron series only made it up to 3000+ on Socket A. Unless they made a OEM 3300+ Version.

Does nobody read links anymore? I'd be glad to post a screenshot of CPU-Z on the one I'm running now, too.

EDIT: Text - When I get my new RAM I'll do the same for my Athlon XP 3200+ and do the same, see if I find any differences there.

A Sempron is a rebadged Athlon XP, but the performance rating is relative to the Celeron, instead of the Pentium 4, as the Athlon XP is. The speed rating difference is about 300, so a Sempron 3300+ is about the same speed as an Athlon XP 3000+.

Tells me nothing of my question. BTW my Sempron 3300+ (CPU-Z pic above) is the same caches, voltage, FSB and clock speed as my Athlon XP 3200+.
