The ATI Radeon 5XXX Thread

[LowRun]

Even a dead clock is right twice a day.

Then i guess he's far from being a dead clock.

[Calmatory]

this thread has lost all coherance...

True. Thank AMD for keeping everything secret!

If the current leaked specs are true we will be looking at a GTX285 x 2 and maybe a bit more. But we dont know enough about the GT300 to know that for sure.

not really, 5850 seems to be beat a 285 but not by much... and a 5870 wont be 2x as fast as a 5850, i think we can all agree on that

I think you should take a more detailed look to the performance comparisons (particularly the ones with numbers and resolutions and all): HD5850 is beating GTX285 in nearly all games (including STALKER CS and Crysis Warhead), some by more, some by less, so no way that the HD5870 is not noticeably faster than GTX285.

On the other hand, in the comparison between HD5870 and GTX295, you can see that STALKER CS runs 38.4 vs 40.5 without AA and 24.2 vs 22.3 with 4xAA (so no 20% lower, even higher with AA) and Crysis warhead is 51.5 vs 53.6 and 43.6 vs 48.5 respectively (~3% and ~11% performance difference respectively) so...

In general, the difference between HD5850 and GTX285 (favorable to the Radeon) is equal or greater than the difference between GTX295 and HD5870 (favorable to the GeForce, if we don't count 8xMSAA results). So we could say that GTX285 is trading blows with HD5850 (favoring the ATi card) and GTX295 with HD5870 (favoring the NVIDIA dual card).

You can take a look to this post if you want to examine better the leaked benchmarks: http://www.xtremesystems.org/forums/...&postcount=892

Of course, you should note that maybe a change from GTX295 to HD5870 is not so greatest performance wise (probably consumption, heat and price will be another thing), the same way that a change from HD3870 to HD4650 is not. If you want to see if changing from a dual high end chip configuration to the new generation is a gain, you should wait for HD5870 X2, or make an idea with a HD5870 CrossFire (wich here you can see how it scales, destroying a GTX295 SLI -as it's to expect given that the NVIDIA configuration is a 2x2=4 chips scaling, so much harder to scale).

i think you misread my post, i said:

upgrading from a 285 to 5850 doesnt make sense i think
upgrading to a 5870 maybe...
but from a 295 to a 5870 again doesnt seem to make sense, on the contrary...

5850 beats 285 but not by much
so going from a 285 to a 5850 doesnt really make sense...

upgrading to a 5870 MAYBE makes sense...

upgrading from a 295 to 5870 would actually be a step back... unless your just into benching and want hundreds of fps... where you really need extra gpu perf to get acceptable playable fps, ie demanding games, the 295 seems to be about the same or faster than the 5870.

but like i said, thats probably with amd cpu at stock speed... and as anandtech recently uncovered, some games seem to get a notable perf boost on nvidia gpus when bundled with an amd cpu for some reason... that might actually bite amd in their own pr arse in this document

For an entusiast, crossfire using 5870 is a great price/performance alley.

I still wanna know what does it take to fully take advantage of HD5870 CF? A core i7 @4.0Ghz at least?

Impossible question. It is matter of TASTE actually. In some situations, CPU can be somewhat slowing down, in some situations the GPU. And in some situations the actual "bottleneck" can be the PCI-E bus.


It depends on:
software/game used
settings
the actual scene in the game
drivers
GPU/VRAM speed
CPU/RAM speed
PCI-E bus bandwidth.

So yes, talking about "CPU only" here, it is practically impossible to say accurately. There will always be someone arguing about it. Maybe a 4 GHz i7 can sustain it most of the time without causing major bottleneck, but for sure 7 GHz i9 with 8 cores would do MUCH better still. No one knows, a matter of taste and opinion.

And before someone comes raging that "omg put slow cpu and your fps drops"(sure it does), I suggest "you" to imagine WHY it happens. Hint: Time spent(per frame) by: CPU(both processing and data retrieval from RAM), PCI-E bus data transfer latency, GPU(both processing and data retrieval from VRAM).

Yeah, less than a week in working days.

Could be, but it depends a lot on resolution. At 1920x1200 (or better, 2560) I doubt CPU is going to be a big bottleneck. And if you are using a lower resolution then you certainly don't need two 5870's. In fact, you don't even need one - a 5850 or even a 4870 is enough at 1680 and below

simple answer, yes.

you can check some numbers from people who do overclocking over the top stuff and see how the scaling goes.
Its also a matter of resolution, I would assume, that 1920x1200 is actually a little to low resolution, unelss we go for the 3 screen set ups.
Its a great idea, ati makes a card have a feature, that adds more fps, but what to do with all that power?

Run quake at 1000fps?
No, they spent some time, talking to Samsung, guys we wanna make this feture we call eyefinity, so, if we do that, and you make a special set up, you cut us in for a deal?
Samsung, hum what is it?
ati: Its where our cards are so powerful we needed to add a feature so people would buy more screens to use that power, and guess who they wanna buy from?
Samsung, hum who?
Ati: The guys making screens with thin bezels...
Samsung, you think so?
Ati: come and sit down and play this game here.
Samsung representative: OMG!
Ati: yes we know.

As "Calmatory" wrote, it depends on a lot of factors.
If they increase the gpu-use of computational work (OpenCL or whatever) the burden will be higher on the gpu.

With tesselation I think that it will be easy for a slow cpu to bottleneck the gpu.

Nvidia confident that GT300 wins over 5870
A few people confirm

Nvidia is still not giving and hard details about its chip that we still call GT300 but one thing is getting quite certain. A few people who saw just leaked performance date of ATI's soon to launch Radeon HD 5870 have told Fudzilla that they are absolutely confident that GT300 will win over Radeon HD 5870.

Since GT300 has its GX2 brother they should not fear much against Radeon 5870 X2 whenever that comes out, as if Nvidia wins a single chip battle, they can win the dual one as well.

We can only confirm that GT300 is not a GT200 in 40nm with DirectX 11 support. It’s a brand new chip that was designed almost entirely from the ground up. Industry sources believe that this is the biggest change since G80 was launched and that you can expect such level of innovation and change.

The launch as far as we know is still slated for late November and hasn’t been confirmed.

does Nvidia have eyefinity support?
if not, dosnt matter how fast they be.

I do agree. The HD5870 will only be 15-20% faster. But that is where is HD5870 X2 comes in to play. Depending on the time nVidia needs for its GT300 GX2 (if there will be a GX2) Its also possible that AMD will have a refresh of the RV870 (HD5890 / HD59xx ish)

At the start i think it will be HD5870 and the X2 VS the GT300 Single card range.

It's beginning to sound like the 4870 vs GTX280 all over again. Nvidia will have a GTX360 to compete with the 5870, and a GTX380 to out perform it by 15-20%.

So it's just a repeat of last gen it seems. Now it all depends on price.

These are kind of my thoughts... but I'm ok with that because I do not want to pay the price premium for the nvidia part again.

I bought the 8800GTX when it came out for $650... so now I use ATi

So true. Why pay 50% more for only 15% performance increase.
I hope ATi/AMD stick with the 4x00 business model.

They need to price 5870 at $299 to sell lots of cards.

indeed - i want one either way but obviously the lower price is better
