View Full Version : R520 specs +spy pictures
All i can say is :drooling: I wonder what Nvidia are going to use to counter because we have to assume this will be better than the GTX and i love dual slot cards.
Yeah dual slot is cool as long as you dont have 2 of it in your mobo.

See I like dual slot cards too. I mean, it's neat to have a nice slim graphics card, but a dual-slot cooling solution is not a big deal to me at all. People sure do get bent out of shape about them though. :D
The return of the dustbuster :) But yea, dual slot cooling doesn't bother me in the least. If you put a card next to your graphics card, you are asking for problems anyways. Usually I keep at least 2 PCI slots empty.
Yup, thats what I saw at e3 playing Alan Wake... it lagged at several parts.

That was an early "leaking" enginering sample. :D :p
I think they've had 2-3 revisions since then.

But weren't the early samples supposed to be using higher clock rates and more pipes? That is, I thought they started off trying to have a much faster card but have since scaled things back a little.

yeah, but with a design that is under-featured anyway, there is only so much it can handle

According to David Orton there weren't any features pulled out of R520 and I guess that applies to the number of pipes as well,whatever their number is.
He also said that they've had problems getting high clocks but the problem has been solved.
Its really hard to find any solid info.

How do you know the design is faulty?

not thats it faulty, its just not expanding in the direction thats software is going. Shaders are the big craze in games, and having more vertex shaders (and pixel pipelines) allows for more detailed shaders. i'm not saying ATI's card isnt going to be decent. i am sure it will be, but the thing i see is that, to make up for having fewer things onboard, they up the clock speed. this is great, but it creates a yeild problem. it's easier to make a ton of slower chips that are stable instead of faster ones
Ati's shader performance has been pretty solid for their last two gen products and actually a lot better than nvidias.Have they struck out this time?Remains to be seen.

IPS = IPC * CPS
Shader intensive games don't in and of themselves require more pipelines, they require more shader power (instructions per second). There are two ways to achieve that. All else being equal (which it isn't of course) a 400MHz 24 pipe design and a 600MHz 16 pipe design could have roughly equivalent "grunt".

i totally agree. i am very very interested to see the performance of the upcoming cards
Shader Performance a lot better than 7800GTX? That's probably very difficult :rolleyes:

Ah, okay.
Yeah, I hesitated to even post anything since I was so unsure on what is solid info and what's not.

Both the pics are frm HKPEC. Then why is the color of core different in both the pics? one has Dark Blue, while other is Black..?!?!?

It looks like the core is glossy and is probably reflecting camera light. NV cores are a very shiny silver.
I thought of that before posting.
But then, look at the pics again.
no matter from what angle the pic is cliked, the core is BLUE. Its not reflection..im sure abt it.
either Vr-zone's pic or HKPEC's pic are fake. but both are stamped with HKPEC.. Maybe both are fake?!??!
The backside of a silicon chip may be covered with a thin bluish layer of protecting oxide. Or it may be a protective/thermoconductive paint.
Also the first two photos seems taken from a "product description" brochure (white background, flat light...) thus they may be doctored to enhance details
Oh I see, I was confused like many people from Rage3D forum, I guess that mean R520 is still 256 bit graphics and memory but only 512bit memory transfer, I think that do not make sense, it probably will give less or no performance improvement over 256bit memory transfer. I believe 512bit memory transfer will require a 512bit graphics chip and 512bit memory interface, looked at completed 256bit Radeon 9700 Pro for example.
I believe it was the other way round it had 256bit memory with no improvements like Hyper Z or tiling etc but the core was 512bit.
If you use Multi sample FSAA then the load is mostly on the GPU while super sampling is very bandwith intensive but looks the best.
However i don't quite get the internal 512bit interface i would if they mean
that is has something like xMB cache running at 512bit? Should increase the permance of HDR which is a bandwith killer hopfully Crossfire will work with HDR which SLi doesn't seem to and frame rate are hairly low :(
Shader Performance a lot better than 7800GTX? That's probably very difficult :rolleyes: Yes and no, shader peformance is better clock for clock however the 7800 has more rendering pipelines so the 7800 is better in the end.

What's wrong with the LE ? It's just a way to re-use the defective chips. :rolleyes:
...and they must have ****loads, considering the yields ! :angel:

Yeah I dont get R520 XT and XT Crossfire Edition memory, I dont think it will work well when R520 XT have 512Mb RAM and the XT Crossfire Edition have only just 256Mb RAM, that do not make sense.
