hd6570 ddr3 vs hd4670

[621ogob]

Hey Guys,

I'm a newbie here and have a question:
Which graphics card is better: hd6570 ddr3 vs hd4670 ddr3 ?

I wanna choose one of thoese, co please don't suggest me other cards.

Thanks,
ogob621

What price? For what purpose? HTPC, the 6570 wins hands down.

My purpose is to build as powerful computer (for playing games) as possible. Price is irrelevant here, coz I can get these cards for free.
I understand that hd6570 ddr3 is better for HTPC, but what about games ?
I know that hd5570 is eqaul/a bit slower than hd4670, but what about hd6570 ?

The 6570 will win easily, but neither of those cards is particularly good for gaming.

Smartazz, please state your reasoning. I mention hd6570 DDR3. Hd5570 is equal to hd4670 at best. The only difference between hd5570 and hd6570 is more shaders (80) and more TMU's (20 vs 24). You think that makes so much difference ?

I had an HD4670 a while ago, and it was quite an overclocker and I'd be hard pressed not to recommend it since it will deal with higher resolutions and textures easier. The 6570s GFLOPs advantage won't mean much of anything without the memory bandwidth that GDDR5 would provide.

Also I think it comes down to what you wanna play. My experience with my old 4670 and the 5570 I had in another computer were pretty good. The 4670 I think was better though. It's higher base clock and OCing capability resulted in better performance overall, and certainly having more TMUs helps. Both GPUs could play Crysis on high in DX9 quite fluently. Turks extra GFLOPs would come in handy for VERY shader bound titles like Metro 2033, but something like Crysis which in general has a very large balance of geometry, textures, and shaders needs something like an 4670 where the texture throughput is very high in comparison to the GFLOPS.

What memory speeds?
The 6570 has more horsepower, but with DDR3 versions they could both be memory speed constrained. These cards have the horsepower of a 9600GT/8800GT, but a 9600GT/8800GT has 57GB/s bandwidth while even a 1000MHz 128bit DDR3 only has like 30GB/s. I'm seeing a lot of 667MHz and even a 500MHz DDR3 6570 on Newegg.

I'd say go with the 6570 if the memory speeds are within 20% of each other. Greater than that (667MHz vs 1000MHz 4670, for example) and I'd go with the 4670.
If you don't know the memory speeds for each, go with the 6570.

Hd 6570 is clocked: core/memory - 600/900(1800 effectively),so difference isn't much. I'm only concerned with TMU's right now: hd6570 has only 24 whereas hd4670 has as much as 32.

On the net there are many reviews of hd4670 and literally NONE of hd6570 drr3 (only with gddr5). Can I assume that performance of hd4670 = performance of 6570 ddr3 and see every test of hd4670 as test of 6570 ?

D:

Jesus that is low. 4670s are 750 MHz stock.

The 6570 has 480 shaders clocked at 650MHz and the 4670 has 320 shaders clocked at 750MHz, which makes the 6570 roughly 30% faster(480GFLOPS vs 624GFLOPS) in terms of compute power. The memory bandwidth of the 6570 is also better than the 4670, even if it's close. Keep in mind that the 4670 is also a 55nm chip and the 6570 is a 40nm chip.

The 6570 has 33% more shaders at 13% slower clock speed. The memory bandwidth on both are low enough that it wouldn't really matter which you used for the more severely memory-limited games. And the 6570 is 2 generations newer, so it will support more recent software and has better driver support.

All in all, the 6570 is the better choice.

The 6570 has 50% more shaders(480 vs 320), but I agree that the 6570 is the better choice.

If the 6570 you're looking at is 900MHz memory (not all are), you'd want that over a DDR3 4670.

Ah, my math was off. Oh well, same point.

 

[621ogob]

Ok, lets sum up:
1) hd6570 has 50% more shaders (480 vs 320),but hd4670 has 25% higher core core speed (750 vs 600).-> hd6570 is better
2) bandwith is similar
3) number of ROP's is the same (8)
3) hd4670 has 33% more TMU's (24 vs 32) -> hd4670 is better

And the final question: what's more important: shaders vs tmu's ?
Of course, we can finally assume that hd4670 = hd6570.

What's your opinion ?

 

[Red Hawk]

The Radeon HD 5570 had less shaders than the 6570 and less texture units than the 4670, but it was still a fair bit better than the 4670.

Since the 6570 has significantly more shaders than the 5570 it should be clear that the 6570 > the 4670.

 

[621ogob]

Red Hawk,

Unfortunately, things aren't that simple. Hd5570 test by Tom's Hardware is strange, coz it's the only one claiming hd5570 is more powerful than hd4670 by so large margin. IMO quite reliable are following charts:

Pclab is non-eng site, but I find it quite useful.
In every given game, hd5570 is worse,see ? That's why, I wonder if its successor hd6570 overperform hd4670 ?
