Ati hd2400xt works with hd3300 790gx crossfirex

[dafunklull]

WHO KNEW!
I had this old wee little 2400xt around the house for months and all the time iv been hunting for another hd3450 to hybrid with....

I was aware of crossfires flexibility in pairing but it was always match the first 2 digits of the card moniker.
ie hd4650 will work with hd4670 or hd4830 working with hd4870 and even with a hd4850

except for hybrid crossfire.
2400xt/pro/hd3450/hd3470 crossfirex with hd3300igp

but the hd3200igp wont hybrid with the 2400xt but will with the hd3450
in the limited testing time i had with it. iv seen it work with the hd3200 and hd3450 card under windows xp with cat 8.8.

this is my first post here this isnt any sort of help need but a friendly random heads up on what seemed to be uncommon knowledge as all the ati crossfire charts iv seen as of late neglect to include any models pre hd3000 series.

mind you the crossfirex gains of having the un overclockable 2400xt and the highly overclockable hd3300
are pretty slim

aquamark3 as my benchmark the default benchmark no settings tweaked or over clocked catalyst to balanced.

2400xt on its own 700mhzx700mhz -29,521
hd3300 on its own 700mhz/800mhz as its using my systems ram. 32,174
in crossfire x 60,045

while not bad is still highly inadequate for anything released to date. and only at 800x600max resolution
for comfortable fluidity of fps...

Nice find and the tip off to this is that internally they are all the same code wise except you won't have DX10.1 support and only DX10 normal but the differences are nonexistent. What I would like to see is physics running again on a ATI gpu. The last time physics really ran on a ATI gpu like Phsyx does today was on a x1900xt though a forgotten by today feature called compute to shader. It didn't give all the power of the gpu but it was more than enough to do the job. On a R580 gpu the computing power single precision is around 400-500Gflop with 512 threads while the G71 was weaker. The G71 was around 400glfop give or take with 800 threads which was the weakness of the architecture more than it's shader. Both were weak clock wise and they never got to express their real potential. Both were slow on the memory side while the core clocks were far to weak. The 2k series had its strong points but had not ATI's drivers botched their performance they would have performed better then instead of waiting till the end of the 3kseries life before drivers had improved enough for them to demonstrate their capabilities. The 2900xtx and GT were failures.
