"a Dothan CPU doesn't offer any advantage over its Banias predecessor with regard to gaming performance."

according to the scores, in regards to gaming, dothan actually performed slightly poorer by a few points (not significant) but i thought thats interesting and probably due in part to its larger cache creating latency...

that larger cache tho is what makes dothan perform "22% better" (tomshardware) in certain benchmarks, and that was for rendering/encoding/workstation tests

and while the .09 micron process helps run less at a lower power consumption , the extended battery gains are nominal compared to banias

tomshardware was right in saying that dothan is just an evolutionary step for banias... not revolutionary... which we might see with sonoma / alvisio systems in september...

Well, I am dissapointed and I am glad I did not wait for Dothan.

True...but for those of use who are looking to do photo/video editing while playing a lil' HL2 on the side...it's wonderful to see a 22% gain.

Now....to find the right one...hmmm....

me too

i kinda knew it somewhere inside

whats interesting about dothan tho is that it has 4 VID settings for speedstep as opposed to the 2 settings for banias...

that means it can scale more accordingly for program that require certain workloads...

21w TDP is the max at full speed, and 7.5w (wow) is the minimum tdp for scaled down speed

Keyword... "some". I dont see a 22% in Halo, or UT2k3.

But cant those be throttled already in the current P-M, using Speedswitch XP?

yea he was tryin to not downplay dothan in that respect lol

the 22% gains as enders pointing out is in regards to the benchmaks for rendering/encoding/workstation tests

no gains over banias in gaming perfromance... (if you look carefully at the score, it actually is lower by a few points compared to banias) the reviewer doesnt mention that at all, but i bet my nickels and dimes that its due in part to the larger cache creatin latency

yes its throttled to "low" and "max"

lol

so 600mhz or 1700mhz

to my understanding of the new 4 VIDS, i think it should be able to scale better... like 600mhz, 1000mhz, 1500mhz, 2000mhz

Yep... the reviewer was probably hinting at it when he wrote...

"However, the caveat is that doubling the cache size risks a drastic increase of the number of cache misses, thus reducing the CPU's performance significantly. "

im so glad i didnt buy into dothan hype

i dont do much encoding or rendering or workstation with my laptop

so im glad i stuck with the fastest banias , even if it was for a few frames and few scors higher than dothan in gaming lol

Hehe... poor suckers who have been waiting for Dothan to come out. Hahah...

Yeah...if I wasn't looking for better encoding performance, the 1.7 Banais would be a pretty awesome choice right now for portable gamers. Prices are fixing to plummet to pave way for the new Dothans...Gamers, get out your wallets

So you can buy your Banias equiped notebook for cheap. Of course... this is only if you want better performance than Dothan

did u notice the blackbox p4 with the 9700 ? they revealed its core/mem speed...

back when they reviewed the 9700 with the blackbox and compared it with the 9600 they said th 9700 made 25-30% gains better over the 9600, but that was using the blackboxes 445core, 263mem (which they did not reveal)

i find thats kinda decieving since alot of the 9700s came default clocked at 400core, 200mem and OC up to 460core, 230mem

With my limited knowledge of computer architecture, let me ask a question...

Could it be that we are seeing virtually no increase in gaming performance between the 1.6GHz Banias and the 2.0GHz Dothan because the 64mb 9600 is the bottleneck? If both systems were running a 128mb 9700, might we see a larger performance gap?

no

in the test they used a winbook with dothan 2.0ghz (labeled Winbook D)
and a winbook with banias 1.7 (labeled winbook B)

using the SAME 9600 64 card in both systems

had they done the benchmarks with a 9700 card all the scores woulda been better all around, but between dothan 2.0ghz and banias 1.7ghz, dothan would have been slightly lower than banias by a few score points/frames (as seen when they tested with the 9600 gpu)

i would of like to have seen some benchmarks in games where they require more workload of the CPU like neverwinter nights and quake3.... perhaps that might reveal something not yet realized with dothan

saddest part is that according to the article, actual performance gains from the new architecture seems to be only 5%, the rest is completely due to the high clock speed. what a disappointment...
