7800GTX Enough For X1800 XT

We heard that GeForce 7800GTX will compete nicely against the Radeon X1800 XT therefore we can expect their performance should be pretty close. There isn't a need for NVIDIA to bring out their Ultra version as we learned. In comparison, the 7800GTX has 24 pipelines while X1800 XT has 16 pipelines and the former is clocked at 430Mhz core / 1.2Ghz memory while the latter is clocked at 600MHz core / 1.4GHz memory.

ATi R520 Core Revisions

ATi has decided to go with 16pp R520 with their latest re-taped revision called A1023 so the launch of R520 on Oct 4th has only 16 pipelines for their top lineup X1800XT. We expect ATi to replace R520 quickly with R580 in early next year to better compete with NVIDIA's lineup. The R520 Rev 2 card gotten by us is a golden sample in its early stage originally planned for 24/32pp but very poor yield push ATi to release 16pp R520 instead. Now this card is into Rev 5 and it could be meant for R580 instead. We also know that latest X1800XL core is known as AE revision.


... I suppose every info about R520 from vr-zone is pure BS... am I right?

That a f*cking hilarious ass covering post from VR-Zone there!

As for the numbering system, I already gave you the clues - the common rumour puts RV530 at 12 pipelines, consider what can be considered one of the important elements to constitute a "pipeline" and then look at the configuration 4-1-3-2. RV530, however, may initially land at 4-1-3-1 though, I'm not sure yet.

My new sig should of some use in these threads.

Nice catch no-X.

There are many other price increasing factors you seem to be ignoring. Such as, the 9700 Pro has 128megs, the XT has 512.

Despite that, its still the same MSRP of the 7800GTX, with twice as much ram. If you are going to complain about ATi's price, you should be really upset with NV's.

Memory prices have fallen considerably since then, which means you can get twice the amount at much faster speeds for around the same price. True, it is 512 MB which is a hefty increase, but that still doesn't justify the $600 price point imo.

The GTX price was even more ridiculous, but it didn't last long dropping to under $500 in some cases only mere weeks after launch.

7800GTX Enough For X1800 XT bla bla

All indications seem to suggest the X1800 XT will be a fair bit faster. Of course the GTX at 480, 1300 or higher will compete nicely.

Is this the utter disaster of an explanation that I think it is?

It certainly left me with a "wtf?" feeling. I think I'll give it another read through...

That is a bunch of popycock from those guys...

When will the madness end?????

I know, i know.

soon.

Well, they already did it once more than a month ago (the infamous 3% yield post), and rather than slink away quietly, hoping everyone would forget, they had to go and dig themselves in again on 24/32, and now have to back/fill again, much closer to release while everyone else's data is getting better!

Well it looks like ATI has failed yet again. The R520 looks to be out dated even before it hits the shelves.

Oh well I was really looking forward to this card.

Guess I'll just have to get that 7800GTX.

Umm, you're basing this on unfounded speculation and without reading one benchmark test?

I will wait for the tests but it looks like I will be getting the Nvidia card.

You'll see at lot of this, and I'm expecting to see a lot of it in the shop. People think more pipelines = much more performance. They dont know how to consider other, less easier to explain, parts of a GPU that really help performance.

As for personal thoughts. I'm curious as to what tweaks have been made to the pipelines, and other areas, also it sounds like R520 could be pretty damn feature packed as far as standard boards go with none graphics only tasks (encoding/decoding etc). I'm also curious about the memory bus, and what the external and internal buses mean, as I really dont have much of a clue here.

It'll be interesting, and even if it doesnt beat the 7800GTX, it'll be a very interesting source of GPU design.

But I'm not sure, if X800GTO is the only new piece of HW from ATi, which we'll see these days...

 

[John Reynolds]

Exactly. We're hitting the point where high-end graphics boards can drive new games at 16x12 (my LCD's max res.) with AA + AF, so usable/useful features logically become more important (at least to my thinking).

That is the second person handing out the verdict even before the release.

OMG, please say you're kidding me?

How can we know ANYTHING about how the R520 & 7800GTX match up?!? I don't see what you're basing your decision on.

I read somewhere yesterday that the x800 GTO was launching in 2 days (as in mass avaliablility), so I'd assume thats what that is refering to.

There's nothing to base that on but if they do match up it means that the "pipes" on the R520 are a lot more powerful than those on the R420. Due to architectural differences, Nvidia was able to remain competitive even at a significant "shader-fillrate" (=clock x pipes) disadvantage last generation. But a 600x16 part is not going to have that numerical advantage over the G70. Which means that, architecturally, the R520 has to have similar or better bang per clock than the G70.

PE 540x16 = 8640 | Ultra 400x16 = 6400 --> 35% to ATi
XT 600x16 = 9600 | GTX 430x24 = 10320 --> 7.5% to Nvidia

Quite a leap IMHO.
