X1800XL vs. 7800GT

http://www.hkepc.com/bbs/viewthread.php?tid=477628

... about 7.000 for the XL ... seems a bit low IMHO

BS?

Looks legit enough for me, although a driver release to co-incide with CF and the new R5xx series release could make a difference (if it exists).

What is interesting to me though, is that the X1800XL runs at ~500MHz core and ~1,000MHz RAM. Add 100MHz for the core and 250MHz for the RAM to get XT speeds, extrapolated I get ~8,700 '05 for an XT.

Not bad, if true. I think I'm getting ahead of myself though.....

It is the x1800pro that runs at 500/1000Mhz - the x1800XL runs at 550/1250Mhz - so these scores are very bad indeed, they indicate as good as no effiency improvement. If these scores are true Ati could be in big trouble, unless the picture changes dramatically with highres, AA and AF.

Another thing is these scores does not fit with the x1300LE scores posted before, where we saw a dramatic effiency improvement.
 
From the recent Ati roadmap, R520 is not much higher up the performance axis than X850. RV530 is at X800 level & RV515 is at X700/X800GT level. Of course, that could just be marketing...

Ah. My bad. Although the 7800GT benched is overclocked apparently; the 7800GT at default speeds normally gets ~6,600 in '05 with an A64 4000+ and 1GB dual channel:

X-Bit Labs: NVIDIA GeForce 7800 GT in 3DMark '05

An overclocked 7800GT gets over 7,200 in '05:

BFG 7800GT OC @ 425/1050

So if the X1800XL gets 7,000 at default speeds, it's all good baby!

Just compare these 4pp/16pp 3DMark05 scores...

x1300 (4pp) = 2900 / x1800xl (16pp) = 7000 ... ratio = 1 : 2,4

x800ve (4pp) @540/550 = 2790 / x850xt-pe (16pp) @540/560 = 6460 ... ratio = 1 : 2,3

So XL's score could be real.

It is not all good , it makes a X1800XT (625Mhz core, the conclusion might change if the clockspeed changes) less than 30% faster than a x850XT PE. The difference between a 7800GT and a 7800GTX is a lot bigger than the difference between a x1800xl and a x1800xt. Also remember it is the X1800 Pro that is prized at the same pricepoint as the 7800GT not the XL.

OK 3dmark05 is a bit atypical, it might not usefull to draw general conclusions about the performance from 3dmark05 scores.

Fair enough. I just hope ATi drops the prices sooner than later.
 
Once again we are led to believe from "industry sources" that TSMC's R(V)5XX yields are suboptimal, whereas Dave Orton has publicly been saying the opposite. Would these UMC ASICs be any different from the ones about to be launched?

R480 = PEG / R481 = AGP
R520 = PEG / R521 = PEG(?)
 
Still can't ponder why people take this stuff
a) seriously
b) like it's the gospel......

Guess just chalk it up to silly season!;)

RV530, Radeon X1600 to come in December

http://www.theinquirer.net/?article=26470

THINGS ARE finally starting to make sense. ATI has just announced the Radeon X800 GT and GTO cards and it took us a while until we realised how this card can co-exist with upcoming RV530, Radeon X1600 series. The real answer is, it won't.
ATI plans to volume ship the GTO until the end of the year. RV530 won't see the light of day until sometime in December. Therefore you have to fill the gap with some other product that can make Nvidia 6800 standard and 6600GT run like a fox for cover.

The second part of the story is that ATI actually has great volumes of both R430 and R480 and wants to use both chips for Radeon X800GTO and GT cards. How convenient.

So when it comes to the mainstream and Shader Model 3.0 from ATI, you will have to wait a few more weeks than expected but we can confirm that some of the R520, Radeon X1800 series and all of the RV 515 Radeon X1300 will be available in quantity.

Nvidia is planning a counter attack, of course, but we suspect some massive price cut on its existing parts, at least until the new mainstream and low end cards are ready. µ


..... no X1600 till dec.??? Could this be true? I don't believe it.
 
Nothing would surprise me at this point. Perhaps RV530's performance is good enough that it would somewhat "upstage" the 16-pipe R520 and they prefer to launch it closer to R580?

It just doesn't make sense to me that despite taking a $70M inventory writedown, ATI would still have enough R430/480 silicon to need to delay the RV530 launch by two months.
