7800GT clocks=335Mhz/1100MhzRAM $499

[mesyn191]

Kinda pricey for what you get :stick: ....

Hopfully that is just a early adopter intro. price and it goes down when R520 gets introduced or maybe even a little before hand. Seems like its got some serious potential for overclocking though I wouldn't be suprised if you had to do some volt mods on it to get really high(I bet it'll be the king of phase change vs stock clocks...), and now that nV has decided to give it SLi support doesn't seem to be much of a reason to get a 7800GTX.

Supposed to be on the shelves and in stores in quantity by the end of the week.

Where'd you hear this?

[Playful_Buffalo]

that core is over 100mhz then some GTX's...you think that they lowered the stock voltage a bit?

[Vapor]

They must have....these GTX clock so well and this is so much further down

[Vapor]

I wouldn't be surprised if they dropped the voltage down to 1.2v to prevent most OCing.

[LowRun]

They should be identical to the gtx except for the ram so maybe it will only be a matter of bios mod to get decent GPU volts.

[Geforce4ti4200]

those are clocked alot lower. Must be speedbinned as failed 7800gtx. That and only the gtx from what I hear supports sli. $100 isnt much of a saving for much lower clocks

[mesyn191]

Nah they changed they're mind a few weeks ago apparently now the 7800GT and the 7800 will get SLi support too.

$100 savings isn't great like I said, but its not bad, and if the card OC's well, all the way on up to GTX speeds on air on stock HSF then I'd say its pretty decent. We'll just have to see.

[JohnyKnoxville]

seems pointless, why not just pay the extra $100 and get the best? I mean when you are spending $500 what is another $100? but my opinion.

[Gryph]

That card should be 399 at most. I guess they are price gouging while they can get away with it.

[mesyn191]

Yea I think so too, that is why I'm going to stick it out with my crappy 6200 for another few months til' they do a price drop....

[Vapor]

This is expected to outperform a X850XTpe and cost at least $50 more??? Hrpmh....I was expecting lower mem speed and higher clock.

[mesyn191]

Nah, the core is bandwidth limited most of the time, so having a approx. 33% lower core clock and a approx. 9% lower mem. speed should allow it to hang in there with the GTX at stock speeds quite well so long as you don't go crazy with 8xFSAA. If they did the opposite and had the core at close to GTX speeds but 33% lower mem. speeds then it'd perform like crap.

[metro.cl]

hmm if this overclock at 7800gtx speeds its a nice thing, if not i would just buy the gtx.



p.d. any one read the new about 7800gtx auto overclocking about 60mhz on the core??

[shadowing]

This seems a bit decent. However, I would rather much get the 7800GTX. a $100 more and a LOT more.

[mesyn191]

Yea metro I read about that, it sounds almost like what Intel does with the Itanium and Foxton (temporarily OC's the core by a certain fixed amount in situations where you're GPU bound instead of bandwidth limited). Sounds kinda cool actually but it might make overclocking difficult under certain situations and makes benchmarking results questionable depending on what else nV is doing with thier drivers when the core does that...

this with the new athlon x2 3800 mid range killer system

[Kanavit]

i'm still recovering from the $550 i spent on the e-vga geforce 6800 ultra.

[Cybercat]

HA! I just realized that the X850XT PE will have a 7% higher fillrate than the 7800GT. This card seriously isn't worth $500, IMO.

[Flak Monkey]

Actually the X800XT has a higher much fillrate than even the 7800GTX. It's because you dont calculate fillrate as Pipes x Clockspeed, as most people think, but as ROP's x Clockspeed. In an early draft of the reviewers guide I also listed pixel fill rate as 10.3G Pixels/sec (thinking 24 pixel pipes x 430MHz core). While that's certainly the bilinear-filtered texel fill rate, Tony corrected me stating that for peak pixel fill rate, we'd multiply number of ROPs x core clock rate, since "pixels" are output from the ROPs, so it's really 16x430MHz = 6.88GB/sec. Given the number of times fragments might cycle through pixel pipes, we really didn't need to increase # of ROPs to maintain a balanced architecture.

While important fillrate isn't the end all be all of performance though. More and more games are becoming shader bound, not vertex or fillrate bound and I think nV and ATI know that (just take a look at what ATI is doing with Xenos and what they have planned so far with R520...), so rather than waste die space on ROPs to get insane fillrate that'll probably never be seen in game except in corner cases that can be designed around they improved shader performance and put in proper HDR support (fp32).

Like I said earlier 7800GT is kinda pricey for what you get, but really doubt that its performance is going to poor.

That is the new boat I have just boarded :(

Not sure what to do...buy the X, or wait for ATI to fire back to get prices falling.

Interesting point. You rarely hear the amount of ROPs mentioned in an architecture because most people take for granted the fact that the ROP count will equal the pipeline count. With the G70 things are different.

[mesyn191]

Yea, I didn't know that either, guess you learn something new everyday...

[gundamit]

More choices is always great, but there is no way that price point will hold. Just wish ATI would get something new out the door so we could see a dramatic drop on the Nvidia line, instead of a slow march downward. Look for more vendors to bundle extra stuff into their 7800GTX retail packages so as not to violate thier MSRP. Next will be rebates, then some cracks in the MSRP.

[zippyc]

Yeah, I know...thread revival. :)

But I just got one of these 7800GT's (PNY) up to 504 core without any mods or higher volts. This yields performance above the stock 7800GTX. The card was $450.00 bundled with a 512K thumb drive at Comp USA.

I am seeking a volt mod for the GPU. MSI claims to have voltmod ability built right into the driver set for their 7800GT, but those drivers are MSI specific.

Anyone know of a software utility that will allow adjustment of GPU volts?

Is there a hard mod I can do on the Power IC to get better volts?

Anybody know?
