Amd Sempron or Amd64 Le

Post by elec999 » Sat Dec 01, 2007 11:55 pm

Anyone tested the amd le new cpus to see how well they do with their power usage.
Thanks

Since the 90 nm Semprons set the pace for cool-quiet-cheap ...it's logical that the 65 nm versions are somewhat better.

In terms of power...these do match up with the Bartons of not long ago at way less $ and while obviously better Wattage draw-heat output-quietness. Aside from the expense-bother of a laptop chip....the Sparta series is probably the best yet for gettig pretty up to date performance while building a near silent rig.

Naturally....these won't be the Gamer - hot rod chips.

A big question we'd love answered is how does the Sparta stack up relative to the basic dual cores from AMD and Intel.

All the focus is on dragstrip bencmarks for big $ gamer-server chips. We need a good analysis on the OTHER end of the spectrum...low heat..watts vs performance + price.

Meanwhile..we can just guess at the details.

I have 2.4GHz A64 LE1620 coming from Newegg, and I just put together a Pentium E2140 system last night, and I plan on comparing both with my 2.4GHz S754 Athlon 64 3400+ "E3". I already sold my 65nm X2 3600+ (very disappointing).

Don't take the TDP numbers too seriously. I doubt the LE1620 is at all different than the ancient S754 "E3" stepping 3400+ as far as power/performance--outside of the different memory configuration.

FWIW: Nothing can beat a S754 Sempron 2500+ for cheap/low power system, but with DDR2 being almost free, it is hard to consider building anything with DDR now.

If the 65nm AM2 Semprons were closer to $25 or dual core they might be more interesting. AMDs 65nm design seems to suck relative to their excellent 90nm design, so I wouldn't choose one chip over another because of that.

The Sempron LE-1250 is based on the improved G2 65nm stepping, which incorporates a much improved memory controller. Performance is apparently up to 6% better than the G1 stepping. In addition, the G2 stepping offer much higher frequency headroom and better undervolt capabilities. It's still pretty expensive for a single core CPU, but I'm thinking of getting one just to play with it. Power consumption should be really low after undervolting it.

The 90nm Athlon 64 LE1620 is working very well for me. How about 3.0GHz @ 1.3V with a stock cooler?

So far the Pentium E2140 hasn't turned into anything. It has been stuck at 1.6GHz as the ASUS P5K-VM I recieved is junk. But the AMD 690G based ASUS board is running well, though I am only at 250MHz HT clock for 3.0GHz on the LE1620.

The Intel motherboard situation still seems pretty poor compared to AMD. I would like an inexpensive and efficient micro-ATX LGA-775 capable of running the E2140 at ~3.2GHz.

Intel platform boards tend to be more expensive than AMD counterparts, especially quality micro-ATX boards. I do anticipate AMD SB700, which would shake nVIDIA's dominant southbridge, I believe. :twisted:

Yes, the two motherboards I recently bought were both ASUS. The barely working one was $80 based on Intel G33 chipset, the nice AMD 690G board was only $40.

690G based Intel motherboards are still available--at least there is the ABIT Fatal1ty F-I90HD available for $92 from Newegg. I might try that, but I am almost ready to buy a ATX board like the Abit IP35-E for about the same price. I think AMD>nVidia>Intel as far as chipsets right now.

QFT.for AM2 boards I can list a dozen+ boards that undervolt down to 0.8v in BIOS, for 775 I have only found two and they are hella expensive.

At least, I would vote for Intel's privileged southbridge, but I couldn't agree with G35's rediculous high price. I would rather get a bottom-lowend discrete VGA to comply with P35. If you mean IGP(Integrated Graphics Processor), well, you got it. :roll:

I've high hope on next year release of RS780 & RS740(690G 55nm evolution) with SB700 combination, and I may upgrade my little 6100 board with one of them depending on price/performance/availability. Let's waiting!
