AMD Sempron: A Fresh Take on Budget Computing

The Test
In looking at our performance comparison, we want to pay attention to 3 different things: how the new Sempron parts do in comparison to Intel's budget line, how the K7 Sempron does against Athlon XP processors, and how the K8 Sempron does against other Athlon 64 processors in 32-bit mode.We only had time to benchmark a few new numbers, so the Athlon 64 that we chose was the 2800+ with the same clock speed and twice the L2 cache.
We used the same platforms in which we tested our Celeron D comparison last month. It is useful to note that we couldn't boot the Sempron on our usual VIA K8T800 based CPU test platform. AMD indicates that there shouldn't be any problems with the new chip booting in current boards, but that some manufacturers are working on BIOS updates that will fix this problem that we had. So this time around, we used a Gigabyte nForce3 250 board.

Thanks to our new and improved graphing engine, our CPU articles will be a little easier to read with green for AMD, blue for Intel, and orange for the processors on which our review focuses. Our graphs will also be a little bit bigger to accommodate large data sets.

"Reliability/compatibility hasn't been an issue for a long time. FYI Intel has had 4 recalls in as many years. AMD has never had a recall"I agree that AMD chips are reliable... but AMD does NOT make chipsets.
There where times in the past that I wished VIA or SIS would recall the crap they sometimes produced. Thankfully Nvidia entered the chipset making business.

yah, gotta wonder where he comes up with a statement like "along with the added reliability Intel offers...". This clearly comes from someone with no experience with AMD products. I personally have no qualms about either Intel or AMD when it comes to reliability. But if AMD offers more performance/$$ than Intel, I will always choose AMD.ThePlagiarmaster - Wednesday, July 28, 2004 - link
T8000, You're kidding right? I'll take an Nforce2 with onboard (asus A7n8x-VM/400 $81) over any onboard intel graphics. We're talking geforce4mx here. It can at least play some games. Intel's integrated graphics doesn't even come close even with the 915G chipset.http://www.tomshardware.com/cpu/20040728/sempron-0...
Jeez, up to 3x performance over Intel's integrated graphics...ROFLMAO. You go ahead and buy that Intel integrated crap chipset. BTW the 865/875 is no more current than nforce2. They are both old tech and both decent (uh, except when comparing onboard graphics...nvidia kicks butt here). Last page of toms review: "In addition, motherboards based on the nForce2 Ultra 400 chipset offer more graphics performance than Intel's 865G platform at a similar and sometimes lower price"
So for $81 (asus a7n8x-VM/400) + Sempron 2800 $120 (which is probably REALLY HIGH...more likely $100 when hits pricewatch or less) we have $200 at most. You said it A P4 can beat it for the same money. Well, as soon as you throw in Intel's integrated graphics it doesn't matter what chip you have...YOU LOSE. But you won't spend less than $200 for a P4 and Integrated board. No way. You'd need a P4 2.4 or better just to cache the chip in speed. The graphics is an absolute loss regardless of choices.
Reliability/compatibility hasn't been an issue for a long time. FYI Intel has had 4 recalls in as many years. AMD has never had a recall :)

"i'm curious how my 2.5ghz barton compares to say a semperon running at 2.0-2.2ghz "Is'nt everyone:)
Socket754 wise I think a sempron is about 10% faster than the mobileXP's at same speeds so 2.2 would probably equal or beat a 2.5 A-XP......Can't wait:):):)

#27I thought about that angle, and while it should work, the fact of the matter is that mpga478 is about to be just as dead as socket 462. If newer Celeron-D's were LGA 775, you could make a case for a better upgrade path with PCI-e and such.
I'm sorry guys, but I'm comparing the Sempron 2800+ with the Celeron 335, which runs at 2.8ghz. I'm not going to compare the Celeron to the Socket 754 3100+, as its name clearly states its a 3100+. If there was a Celeron running at 3100 or so, then I could compare them.
Comparing between the two 2800 classes, there just doesn't seem to be a nail in the coffin. Someone who is going to buy something like this is going to be happy with either one.

Derek anything we'd like to see?Yes. I'd like to see you using good aftermarket HS.
Then I think you can get the celeron D to 3.8 to 4.0.
Also, The sempron 3100 is of most intrest to me..as it's already fast, offers cheap MOBOs like the chaintech, and I think will make 2.6 on air easy due to less cache..
Not so impressed with the socketA semprons as I think the moblie Athlons are so much better both in overclcoking and perfromance. Anyway it would be cool to throw a 2600moblie in there at 2.6..
Thanks:)

"added reliability Intel offers"Where is it? Don't you read the news, Intel now reliably offers chipset recalls and EEPROM updates just for you.
You're either living in the past or should be on Intel's marketing payroll because you reek of it.

"For Sempron Socket 752, I think the added cost of getting a suitable mainboard places it in the price range of a Pentium 4, that will outperform it with ease."Really, can you back that up?
T8000 - Wednesday, July 28, 2004 - link
With these small performance differences, I would say $20 more buys you a current Intel DDR-1/AGP platform (i865 + C335) instead of an old AMD platform (nf400 + S2800). Along with the added reliability Intel offers and the very inexpensive optional "Extreme" 2D graphics you can get, I do not think Sempron Socket A is a sensible choice.For Sempron Socket 752, I think the added cost of getting a suitable mainboard places it in the price range of a Pentium 4, that will outperform it with ease.
So I think there is no reason to be so optimistic about Sempron, especially considering the benchmark selection in this review, that might make Sempron look better then it would in the real world.

Both the K7 and K8 Sempron chips dissipate 62W of power maximally.We hear that mobile chips will be coming out with mobile chips which will be in the 25W-30W range.
I'll update the article with this info.
