AMD Preps First AM3-based Sempron Processors

AMD is preparing its first set of Sempron processors based on the DDR3 supportive AM3 package. The first one, codenamed "Sargas" is a single-core chip that comes across as a single-core variant of the Athlon II X2 "Regor". It features a broad 3.6 GT/s HyperTransport 3.0 system interface, 128 KB of L1 and 1 MB of L2 cache, a dual-channel DDR2/DDR3 memory interface, an up-to-date AMD feature and instruction-set including AMD64, SSE4A, and AMD-V.

Sargas is built on Global Foundries' 45 nm SOI process, and has an operating voltage range of 0.85 ~ 1.35 V. The first SKU based on this core is the Sempron X1 140 (model: SDX140HBGQBOX). It has a clock speed of 2.70 GHz, and a bus multiplier of 13.5x. At that speed, its TDP is rated at 45W. It will be available towards the end of this week, priced around 35 Euro.

Hmm about 50$.. Well, I guess once all the AM2/+ stuff phases out, this will be a decent deal.

wow, this is the first time i've seen sempron, and misread it as "some-pron"


Not a bad little chip, office machines and even media PC's should run fine on a 2.7Ghz single core.

hope they make dual cores with 45w tdp :)

they used to. they just werent semprons, i owned a few in my AMD days.

woo another failed x4
no matter, still has more than enough for regular computing

It's actually a cut down version of the Regor core, which is an actual dual core.

It's actually a failed x2 :P (regor a.k.a. athlon II 250)

Edit: Damn Shadow, fly like a butterfly, sting like a bee much? :D Beat me to it

no, not AM3.

They had them in AM2, so they wont be far off launching them in AM3.


You could always get one and undervolt it yourself.

Junk CPU no thanks...

You can use it with DDR3 for more speed :laugh:

No, it's not carved out of disabling cores in a quad-core chip. At this time I can't say for sure if this isn't carved out of disabling a core from Regor (a 45nm "true" dual-core die).

i dont want to keep it at stock i want to clock it so it eats like my stock 4400+ 65w or something :rolleyes: if you understood me :o

I'm fairly certain that having one core disabled, will allow it to easily hit ~4Gh, considering that the average 250 usually does ~3,7-3,9. Don'k now if it will be any good with games with just 1 core tho...

if it is released at $50, i wonder if it'd be faster than a dual core 7750 kuma? i gotta say i dout it. Most kuma's seem to make it to 2.8-3ghz. So 3ghz dual core? or a guess at maybe 3.9ghz with the single sempron x1? i'd lean towards the dual. should be interesting to see benchies.

EDIT: actually the 7850 kuma is only $60bucks free shipping. most of the reviews seem to manage 3.1-3.4ghz oc on this. i think the 3.1ghz dual would win over a 3.9ghz single.

It should, but then again this one is much more efficient, the kuma was rated at 95W if I'm not mistaking? At 45W it looks like the perfect e-machine, you could probably cool it passively with a bigger case

Celeron E1400 is better...its Dual Core and cheap too sorry AMD, i have a linux system in plan...you don't need beefy hard. for X.

It's an ok cpu, but it really just shows how crippled C2D is without sufficient cache. It's ok for office and internet i guess but FSB+very little L2 cache is a painfull combination in my experience for anything else

yeahhhhhhh having to even respond to them is geting a little old, just makes them look stupid cause they dont read. noobnation.

Nice to see the Sempron grow up and finally get some decent L2.

e1400 does not support ddr3 and comes at 2ghz sempron comes at 2.7 stock + as many said you may clock it till 3.9 or something so they must be the same


is this the regor with a disabled core ?

its a ddr3 chip even with a cheep kit itll be speedy and its 2.7 AM3, what experince do you have in an office with any of the above?? Might not run crysis on high but thats not what its for.

Wait, am I missing something here? I thought the new budget CPUs, ie Sempron equivalents, were going to be named Athlon II?:confused:

DDR 3 have higher latency and it will not run any better with only 200MHz BUS.

I'm talking about the celeron e1400 ;) It uses the Frontside Bus instead of an integrated IMC which means that it will have a much greater latency when fetching data from the main memory. That woudn't be a problem if the FSB ran at a high frequency or if you had alot of L2 cache. Unfortunately you only get 256k per core, meaning that it gets full rather quickly and you have to resort to memory swapping.

It's not a 200Mhz Bus. That's just the base frequentcy. Multyply that by the HT multi of 10 and you get 2000Mz (3,6GT/s) and then I think it's doubled again because of dual channel memory, for an end result of 4000 Mhz. (someone please correct me if I'm wrong)
