ATI's HD2600 has 120 Stream Processing Units

[TroubleM]

I just counted the SPUs from this picture.
Also, it has 128 bit memory bus width like the 8600GT(S).
Nvidia:
8800Gtx has 128 Stream Processors.
8600Gt(s) has 32, so a 4/1(2.5) ratio.
8500 has 16, so a 8/1 ratio
ATI:
HD2900 has 64x5=320 Stream Processors.Link
HD2600 has 24x5=120, so a 2.66 ratio.
HD2400 has 8x5=40, so a 8/1 ratio.Link
It might suggest that HD2600 is just a little bit closer to the HD2900 than the 8600 is to the 8800.

If only it were that simple...

You also have to take frequencies, ratios, etc, into account...

 

[lyssword]

Dam, 128 bit bus I hope it outperforms 1900pro/xt. Unlikely tho..

 

[Munky]

Even with 128 bit mem, it can still whoop 8600gts butt if it's not as cut down on shaders and Ati did not make their cards limited by texture units again.

Well I think we should all wait for the benchmarks for all the new GPU getting released in few days before we start buying new GPU.

8800U
HD 2400
HD 2600
HD 2900

I bet you that 8800GTS 320MB would be killed off and 8800GTS 640MB will be priced at $300. Also the 8800GTX will drop too $450.

why would nvidia reduice 8800gts pricing when nothing comes close to it. as much i want to 8800gts 640 to come to 299 mark (so i can step up) its almost impossible.

 

[krotchy]

You cant directly compare an Nvidia Stream Processor to an ATI one.

Otherwise the HD2900XT would be 3x faster than an 8800GTS, however its only a little bit faster. Also the 8800GTX blows the HD2900XT out of water in FPS despite well under half the stream processors.

 

[rmed64]

Good deduction. 120 stream processors on a 65nm chip with ~800Mhz core speed.....if the texture units and ROPs aren't castrated like the X1600 series, the HD 2600XT should be faster than 8600GTS.

Maybe ATI/AMD is not inept after all

So your saying 8800GST 640 will be priced $400 when HD 2900XT will be same priced. Why would people buy a 8800GTS 640MB when HD 2900XT would kill it in Game perfromance , better vista drivers , also professional driver support for workstation and AVIVO 2.

Heat, noise, Linux support, performance in OpenGL. Not saying these will all once again be wins for green rather than red, but there are reasons to buy a slightly slower product for the same price.

All of this is pure conjecture until enough reputable sites post apples to apples benchmark comparisons and we see street pricing on the parts.

heat and nosie problem are not a problem with HD 2900... HD2900XT runs cooler than R580 and stock fan according to alot of people is quiter than 8800GTX. Linux driver support has been dramatically improved. Open GL performance is not a major problem anymore. All i am telling the person to do is wait for few days before buying a new card. I am also awaiting for a much better review and more trustable website to do a review.

 

[Lord Banshee]

from early benches i would say noise and OpenGL are solved.... Heat and Linux support is another issues mostly still needs lots of work.

Linux driver support has been dramatically improved since last month? That's fantastic news. When I got my X1800XT I had to install Windows to use it. (512 meg was a problem for some reason) And I was still wrestling with driver bugs and missing features 3 weeks ago when the card started to die. It's about time ATI sorted out Linux support.

I'm waiting until the 4th. I've been living with retro gaming (onboard video only) for 3 weeks now, and the shakes are setting in. If there's still no ATI product then NV gets this sale by virtue of having a physical vs theoretical product.

Have you tried to follow Linux installation guide on Rage3d or asked for help on tech form for installation help because i never had any problem with getting X1900XT working on Unbunt or Fedora core 4. Also why would you want to play games on linux too... so much hassel and not enought games work smoothly.

not to mention evga's warranty. to me atleast warreanty i probably the most important thing far more than 3-4 fps.

ATI has several disadvantages outside of raw performance against nvidia, some have been fixed. Nvidia had poor image quality and lost in the high end performance realm last generation. They have fixed their IQ problems and now have regained the performance crown. I'm not sure if ATI expected them to achieve that in one generation.

I loved my x1900xt...but there were several compromises that had to be made for me to go with an ati card.

Heat/noisy cooler: ATI has finally gotten a decent stock cooler on at least some of their cards. This was long overdue. This wasn't the case with the x1900xt I bought. The last generation ran pretty hot with a pretty awful noise level. Nvidia's cooler for the 8800 series is more or less excellent.

Linux: ATI's linux driver performance is terrible. Stability? I don't know...but benchmarks show nvidia parts performing about equal as in windows. ATI parts are nowhere near their windows drivers performance. Nvidia is still the only way to go if you want to play games on linux. Linux gamers are a small piece of the market, but for some it matters.

Board partners: Nvidia has EVGA, XFX and BFG. All offer excellent warrentees (big deal when we're talking about an expensive, hot running video card) with decent reputations and competitive prices. ATI's partners suck in comparison, usually requiring you to pay a decent bit extra to get passable warrenty service. I think this is a bigger deal then people think. Video cards cost a lot of money, and people expect a certain level of service.

 

[yacoub]

wait, why would the 8800GTS 640MB go back up to $400 in price? lol.

Anyway, I think everything this generation other than the 8800GTS/GTX have been a disappointment. I look forward to the NVidia refresh in a couple months and ATi's refresh in the Fall (if they're still around and if they don't delay it to hell like they did with this release).

I look forward to someone releasing a card with 128+ stream processors, 256-bit bus, 96+ TMUs and similar number of shaders, and 512MB of DDR3. That's all I really want in a $350 GPU.

 

[Genx87]

Heh I hope this is a joke. But I saw a thread on Aces that puts the RV630 with 4ROPs and 8 TMU's.
The lowend RV610 has 4TMUs, 4 ROPs, and no Hierarchy Z support.

 

[nyker96]

I wish they actually got some benchmarks for this. But heard they won't be allowing benchs to appear until 5/15 or so.

Isn't the card coming out on the 1st or 2nd of May?
