Discussion On The ATI Radeon 5*** Series Before They Have Been Released Thread

[TheGamingGeneral]

I wonder what the overhead for overclocking is going to be like and if they have actually addressed this complaint people have with the coolers. I had a 4850 at launch, never had a problem with noise, although I guess it was the 4870 people complained about. It did however, act like radiator :/ (the 4850 atleast)

Should get some proper info leaked next week from the briefing.

You think the 5870 will be quicker than a 295gtx in games loadsa?

 

[LoadsaMoney]

Can't see a single one being faster, should be close though, as the 4870x2 isn't much slower than it, but imagine 2x of them in Xfire, gona kick ass

Didn't ask me but I think it won't be. In other words I don't think it will be the "next 8800GTX" but I am pretty sure it will pack a punch.

Dont think im likeing what im seeing so far, if the 5870 = 4870X2
then why are people with 2x 4870x2`s selling them off to get 2x 5870s when they will be exactly the same performance ?

cant just be becuse of DX11 right ?

Probably because crossfire / sli scale much better from one card to two, than from two cards to 4.

 

[LoadsaMoney]

Yeah 2x of these in Xfire would be faster than Quadfire i would think, as a 3rd card doesn't add much, and a 4th adds next to nothing at all.

10 day countdown almost upon us.

 

[TheBlackShuck15]

Dont know yet whether i'm going to go for the 5870 or the 5850. Supose it all depends on how much they each cost.

Exactly. It's a shame that multi-GPU rendering is pretty much limited to two cards and even then support is far from universal. It would be much more impressive if they could get them to scale 60-80 for each card and would no doubt result in more sales.

If Fudzilla believe that there will be a theoretical 0.6x improvement, then the only numbers which work so well when comparing to the HD 4870 is

1200 shaders @ 800mhz. So (1200/800)*(800/750) = 1.6.

Do they really know the real specs? I guess we'll find out soon.

edit:

VR-Zone for example are confused.

They seem to suggest a doubling of shaders, which doesn't equate to only a 1.6x theoretical performance of HD4870 unless clock speeds are severely crippled.

I honestly don't beleive that they'll be 1.6x the performance of a 4870. Especially when you take in to account what they've said about a 58XX being able to drive current games across 3 monitors.

Neither do i, as they'll be slower wouldn't they.

 

[kylew]

1.6x = 60% faster. I don't think they'll only be 60% faster really.

I'm not too sure what you mean lol

 

[LoadsaMoney]

1.6x THE performance of the 4870, makes it slower no ?

I.e its not as fast as the 4870, its only 1.6x the speed of it.

No it makes it 60% faster.

 

[Lightnix]

No. For example 1.6x10 = 16. I think you're thinking of 0.6x which would indeed be slower.

 

[LoadsaMoney]

He said 1.6x the performance though, that makes it slower doesn't it, so its not as fast as the 4870, its only 1.6 of it, either that or ive had to much to drink tonight

Say A 4870 gets 70 FPS in a game and a 5870 was 60% faster, you'd multiply 70FPS by 1.6.

70 x 1.6 = 112 FPS

What you're thinking of is x0.6

70 x 0.6 = 42
