I have 3 MX440 cards here that produce a wide range of performance in quake 3 (same drivers, same Athlon XP+ 1700 running Windows XP machine)
I've used Aida64 to mark down some metrics :
VANV17L1PS MMX440SE Prolink MX440-8x No-name MX440-8x-03913
Bus AGP4x AGP8x AGP8x
GPU Clock 250MHz 274MHz 240MHz
Mem 64MB 128MB 64MB
MemType SDR DDR DDR
MemBus 128bit 128bit 64bit
RealClock 333MHz 256MHz 130MHz
EffectiveClock 333 MHz 513MHz 261MHz
Bandwidth 5328MB/s 8208MB/s 2088MB/s
Q3 1024 dem1. 42fps 158fps 70fps
Regarding the Q3 performance of the cards :
- I would imagine the AGP4x bus would not be saturated on this system with these cards so that should not make a huge difference ?
- Is the memory type (DDR) of the no-name card responsible for the 64bit card to have almost 2x the q3 performance (70fps vs 42fps) as the VANV17L1PS 128bit card ?
- There is a huge jump between the 2 AGP 8x cards. That is purely related to the memory bus (64bit vs 128bit) and the memory clock speed ?
To what extend can you trust readings in Aida / GPU-z when it comes to memory bus , memory type ..... ? Is there a better / other way to retrieve that information ?
I sometimes go to TechPowerUp / GPUZoo but sometimes there is also conflicting information as I guess each card vendor can pretty much do what they want with regards to memory and gpu clock speeds ?
