Interesting. Most review I saw showed that the GT pwn GTS in almost any resolutions. Maybe newer games will show the above picture....... As much as I want to see the GTS 640mb beating the GT (cause I have one!!!), that would not have been an important issue as any games e.g. crysis would not be playable at that setting at 1600x1200. Wonder if the game settings were slightly lower so that the fps would be more playable, would the GTS still beat the GT?  hmm.gif

As much as I wanna see my 2900XT pwn supreme (GTS *and*GT) in DX10 this coming November Catalyst update, I'm not optimistic. laugh.gif

I think it's not enough video RAM. But the tests show otherwise- it's clearly bandwidth limited, with 1600*1200 noAA working just fine, betaing GTS.

Enjoy your 320-bit GTS, still. It runs nicely and not that slow either way. Painful if you bought it at over 350USD though. biggrin.gif

The upcoming 3870 and 3850 wont be beating 8800GT right? Read that somewhere..

I don't think so. Anyway, I still see the GTS640 a great buy if below 300USD (used)
1280*1024 of course should get GT, but 16*12/10 is GTS realm. 19*12 is firmly for the GTXes.

Even with the new "faster/cheating" driver the GT is still slower.

when i mention gts i'm refering to the 320mb version.
However at 1600X1200 obviously all the textures, frame memory everything requires more memory and that's why the 640mb would have the edge here.

Anyway the isn't 640mb 8800gts at another higher price league already?

I think that's true, that's why i said it will be competitively priced if it's at RM680-RM700 compared to 8800gt RM800-RM850.

320MB sucks as always, I advised people quite some times NOT to buy it, and get the 2900Pro for what's it's worth.
whistling.gif Like that actually worked.


Without AA, the GT has no problems. With AA, it just dies off lol. Now you know why nVidia wanted to get the water reflections in Crysis to update so slowly- less taxing on the bandwidth side.

Again, it's not our fault that nVidia's attempt at G92 wasn't as expected (even if it had a 384 bit bus it's not on the GT, and terrible, terrible cooler.) It's also not our fault that the memory was 2Ghz DDR3, not something more spiffy.

I don't know how this goes for the Radeon 3850 (same drop?), but 3870 should be much better with that 2.4Ghz GDDR4.

Huhu, can't try my GTS till I get home mid of this month sad.gif. Luckily I bought mine 2nd-hand. However, still really painful to see the value of top-end cards drop at least rm300-400 overnight......

Really interested to see what DX10.1 can do. I just hope it doesn't kill the fps too much..... hmm.gif

AMD HD3800 pricing shock follows down-clock call

Clock brings pricing down




AMD HOSTED a bunch of NDA press briefings last week in Munich, Milano, London. Since the INQ is traditionally not invited to NDA bashes, we were left out in the cold.

This is what AMD has in store, as far as graphics is concerned.

Phenom pricing details were disclosed earlier by no other than AMD's master distributor, an ASBIS spin-off called ISA Hardware. The 790FX is not interesting since it is already selling in stores.

The interesting part is Daamit's answer to Nvidia's GeForce 8800GT and revamped GTS, the Radeons HD 3850, 3870 and 3870 X2 (R680).

The R680 is the only part planned for next year (January), but we would not be surprised if it appears as a Yuletide present to the hardware community.

The HD 3850 will exist primarily as a 256MB part, while the 3870 will bring 512MB to the table. Some 3850 parts may come with 512MB and some 3870 parts with 1GB of memory -for 20 and 50 USD/EUR above current asking price.

Pricing for both launch parts is very aggressive, and AMD claims it is all due to 55nm process working like a clockwork and achieving excellent yields. Radeon HD 3850 should retail for between $149 to 179 (USD), while 3870 should be between 200 to 230. This is brilliant pricing, going way below 8800GT.

The real truth is that AMD started running into clocking walls (with a selected heatsink-fan combo) and again decided to crash the prices instead of gunning for a better cooling setup that will enable those 800 MHz+ clocks we saw earlier in development.

AMD is touting DirectX 10.1, UVD and PowerPlay checkbox features as key features for selling the RV670 chips.

It remains to be seen why AMD clocked down the parts, so that performance parity with 8800GT is established. Whoever is on Nvidia's or Intel's payrole inside AMD, we have to congratulate that person on a job well done.

This is what will sell as Radeon HD 3850:

* 55nm RV670PRO GPU at 668 MHz (why not 666?)
* 256MB GDDR3 memory at 828 MHz DDR (1.66 GT(/s)
* 10.69 GPixel/s fillrate
* 52.99 GB/s memory bandwidth
* 320 Unified Stream Processors
* 24x Custom Filter Anti-Aliasing support
* ATI Avivo HD
* ATI PowerPlay power saving technology
* Game Physics processing capability (this belongs to fairy tale land, but you know - marketing...)
* HDMI support

As far as higher performing part, the 3870 is considered, specs are following:

* 55nm RV670XT GPU clocked to 775 MHz
* 512MB GDDR4 memory clocked at 1.2 GHz DDR (2.4 GT/s)
* 12.40 GPixel/s fill-rate
* 76.80 GB/s memory bandwidth
* 320 Unified Stream Processors
* 24x Custom Filter Anti-Aliasing support
* 55nm process
* ATI Avivo HD
* ATI PowerPlay power saving technology
* Game Physics processing capability
* HDMI support

These will go on sale on November 19th or a little bit earlier. µ


http://www.theinquirer.net/gb/inquirer/news/2007/11/05/amd-hd3800-pricing-shock
if this is true, then Ati may not win the performance of the 8800gt, but it's still superb value....

Dual 3850 Crossfire on a X38/975/790FX/790X or even nForce (xDNA, haha) = USD 340, aka what you guys used to pay for a 8800GTS 320MB.

(With 512MB, approx USD 170 X 2)

Should beat an 8800Ultra easily. GT pwn what? biggrin.gif

Seems like they're doing another R600 because they can't compete on speed, as predicted. Lower clocks to improve yields and lower prices. At least this time it won't run R600 hot, but perf/watt is still lower than G92.

will the 3870 pawn 88gt ?
if it doesn't, then 88gt will still be the gamers choice at that price ...1.1k doesn't seem cheap to me ...

That's expensive. With that price tag and ATI's need for competition, maybe the 3870's performance is better than the 8800GT? hmm.gif Any benchmarks so far?

so, that turns out to be around RM525-626 for the HD3850 and RM700-805 for the HD3870 ? tongue.gif blink.gif drool.gif
any clue how these two fair with 8800gt?

Either source is unreliable or the HD3870 is performing better than G92 which is unlikely.

Err... 3870 now has a TDP of 105W.
It's very, very close otherwise.
But at this point both GPU archs need 45nm + HKMG to continue using clocks to play out. That isn't happening soon.

105W maybe, but at what kind of performance? At this point it just seems that the G8x has much better perf/watt than R6xx on a similar process. And no one will have hk+mg on 45nm except intel. Everyone else is 32nm or later. NV has at least another higher end SKU in reserve, with higher clocks and more shaders. The current G92 chips seem to be clocked quite conservatively. I won't be surprised if NV releases another lower end G92 part to compete either. It will be interesting to see how it all pans out in the midrange, the price wars are always good.

normally shop will quote on the high price for coming product in order to avoid any dispute from customer
i believe when the 3870 arrive it will be around 1k region

And with that rumored to cost 300USD (or even moar), why is it even a big deal for 2 3850s at 2*170USD?

You said it yourself that the breaking point is the no. of power connectors, and it was in best interests for AMD not to get a faster "default" card out.
When you see the stock GT clocks they don't look *that* impressive too.
It doesn't mean however, that "Superclocked"/"Hyperclocked"/"XXX" etc. editions won't come sooner as the RV670 should be able to get to those speeds with a decent power module (dual slot cooling is there)

10% perf/watt disadvantage on peak load is nothing when you consider that their baseline is much smaller and power saving features do seem to be aplenty.

BTW AMD seems to be making a big, big, big deal out of Crossfire X plus the R680, so I think driver lag/game profile etc. issues would be resolved faster.
