Here are some scores with a fillrate tester from the Quadro FX 2000 (400Mhz core). Quote:
I note the signficant drop in performance from PS_1_1 to PS_1_4. The performance of PS2_0 is quite similar to PS_1_4. Now here are the scores for a Radeon 8500. Quote:
Now here are scores for the Radeon 9700Pro. Quote:

One theory I've read is that the FX architecture is running PS1.4 over its floating point hardware (DX9 compliancy requires PS2.0 to be run on floating point precision) while its legacy shader support (1.1) is using integer functionality from its predecessors (GF3/4). Therefore the FX architecture could very well be faster running PS1.1 over its integer operators than PS1.4, though the former requires more passes.
And, Roscoe, this is getting scary. I'm starting to agree with almost everything I see you post these days. ![]() |

How many pixel pipelines do these cards have?
Radeon 9700Pro Core: 466MHz, memory: 405MHz (http://service.futuremark.com/compare?2k3=330527) Fillrate (single): 2020.5 mtexels/sec # of pipes: 2020.5/466 = 4.33 Core: 324MHz, memory: 351MHz ( http://service.futuremark.com/compare?2k3=299936) Fillrate (single): 1588.3 mtexels/sec # of pipes: 1588.3/324 = 4.9 GeForce FX series Core: 500Mhz, memory: 500MHz (http://service.futuremark.com/compare?2k3=305614) Fillrate (single): 1314.1 mtexels # of pipes = 1314.1/500 = 2.6 Core: 400Mhz, memory: 400MHz (http://service.futuremark.com/compare?2k3=270840) fillrate (single): 1022.9 mtexels/sec # of pipes = 1022.9/400 = 2.56 GeForce TI 4600 Core: 361Mhz, memory: 376Mhz ( http://service.futuremark.com/compare?2k3=237799) fillrate (single): 1003.5 mtexels/sec # of pipes = 1003.5 mtexels/361 = 2.77 Core: 315Mhz, memory: 375Mhz (http://service.futuremark.com/compare?2k3=312725) fillrate (single): 1046.5 mtexels/sec # of pipes = 1046.5/315 = 3.32 Radeon 8500 Core: 275MHz, memory: 275Mhz ( http://service.futuremark.com/compare?2k3=120189) fillrate (single): 656.3 mtexels/sec # of pipes = 656.3/275 = 2.39 Core: 319MHz, memory: 370MHz (http://service.futuremark.com/compare?2k3=239614) fillrate (single): 1024.3 mtexels/sec # of pipes = 1024.3/319 = 3.2 Quick notes to convert to pixel fillrate. For FX/9700Pro, divide the single-texture fillrate scores(mtexels/sec) by one then multiply by the # of TMUs used in each pipeline (which is one). Thus, they are numerically the same. For the 4600/8500, the # of TMUs is also one since the second TMU of each pipe in single-textured cases isn't being used. For FX/9700Pro, divide the multi-texture fillrate scores (mtexels/sec, not shown) by four then multiply by the # of TMUs used in each pipeline (which is one). For the 4600/8500, the # of TMUs is two. If FutureMark didn't waste their time listening to 3dfx and used this marketing term we call "texel", then this stupid conversion equation would not have been needed. Quick observations: 1) bandwidth is the #1 influence. Comparing the 370+ Mhz memory 8500s, TI 4600s and the 400MHz FX shows similar scores, regardless of theoretical maximum fillrate. 2) the FX multi-texture scores in mtexels (not shown) are typically more than 2X greater than single-texture scores. In pixels/sec--remember to convert, this means that the single-texture fillrate is only 61% faster when it should be around around 100% faster than the multi-texture case. Strongly suggests that the single-texture FX scores are lower than it should be, possibly related to #1--bandwidth. 3) double the available bandwidth, you double the calculated # of pipes (notice the 9700Pro scores). Again, this suggests that bandwidth is the issue here. Even with the Pro, the # of pipes don't add up to 8. Where's the noise? 4) the 9700Pro's multi-texture scores in mtexels (not shown) are typically just 50% greater. In pixels/sec, this means that the single-texture fillrate is a whopping 165% faster than multi-texture instead of 100%. This suggest that the multi-texture scores are lower than it should be for unknown reason. |

While it's true I got 3DMark2001 before my Geforce 3... it was more or less to compare the scores for after I bought my Geforce 3 vs my Geforce 2 GTS. My point is, it had nothing to do with Max Payne... matter of fact... I think that game is a POS. ![]() As for 3DMark2003... I prolly won't download it until just before I'm ready to buy a DX9 Card.... but I *Will get it, eventually* (Prolly NV35, R350, or NV40 is when I'll upgrade) /shrug I've pretty much changed my "Video Card Upgrade Strategy"... I used to buy 'Top o' the line' every 14-18 months. Now... I'm just gonna buy "Budget" of DX(?) games that are out. For example... by the time there are an *abundance* of DX9 games out... the "budget DX9 card" should prolly be within the NV40-NV45 area, which will be a buttload faster than my Ti500. I'm getting really sick of spending $300+ a pop for video card.... then a couple months later something comes out that beats the pants off it for less money (Ti4200) I mean... who the hell NEEDS 300FPS in current games???

with all the new cards coming out there will definitely be some price shuffling. |

But I do hear where you're coming from. It's just that I've always looked at it as a tradeoff: - the more advanced language is usually more efficient for programmers but can produce a less efficient binary - the less advanced language is usually less efficient for programmers but can produce a more efficient binary Granted, these are rough generalizations on my part, but I would judge more based on the skill of the programmer than on the language used. That is, I would prefer the product of an elite programmer using C rather than the product of a mediocre programmer using C++. It's all about the end product. ![]() |
