LuxMark has gained, during the past year, a good level of acceptance as OpenCL benchmark. It has been used by AnandTech, Tom's Hardware, Vr-zone and other sites as standard GPU computing benchmark.
AMD has used LuxMark as one of the 5 GPU computing benchmarks to present the new HD7970.

LuxMark v2.0 includes SLG2 as rendering engine with Metroplis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, support for multiple OpenCL platforms (i.e. Nvidia users can use Intel CPU device), ecc.

Our results (defaults scene scala) : older BETA2 result set in ( )
AMD 7970 (Win!) = 1800
Nvidia GTX 580 ("MSI Ligtning" oced @915Mhz) = 1230 , 1230 means first place with one GPU (today, may be cracked ;) )
+ i7-860 @4100Mhz = 1341
ATI Radeon 5870 Mac = 588 + MacPro XEON 3.3 (12 Cores) 1133
ATI Radeon HIS 6870 OS X 10.7.2 = 484 + 2600K 3,4 GHz = 884
ATI Radeon 5770 Mac = 306 (result picked from the results database, not posted here)
Sapphire 6850 = 351 Sapphire 6850+i5 2400 = 670
ATi Radeon 5770 = 315 + Q9450 @ 3.33 ghz = 529
ATi Radeon 4850 = 224 + Core i7 920@3,33GHz = 414
ATI Radeon 4830, OS X 10.7.2 = 151
ATI Radeon 6750M (iMac) = 151 + i5 2.5 Ghz = 384
Geforce 9800GT 512 MB = 78 (88)+ i5 2500K on 10.7.2 -> 325
9600 GT , OS X 10.7.3 Dev 11.D42 = 77 + C2D 3.0 135 ( too slow for listed in the top 20 ;) )

NEW scene room (complex!, >= 512 MB needed!) GPU ony:
AMD 7970 (Win!) = 1028
Nvidia GTX 580 = 591
Nvidia GTX 560 = 302 / 348 with 10.7.3
Nvidia GTX 460 @ 850/1700/2000 = 277
AMD Radeon HD 6870 = 229
AMD Radeon HD 6870 = 225
GTX275 896MB = 122
Geforce 9800GT 512 MB = 50
9600 GT, 512MB(too less!) , OS X 10.7.3 Dev 11.D42 = 41

Incredible:
4 * AMD 7970 GPU got 6153 (win, http://www.luxrender...etail/result/87 )

Added new render.cfg. No speed changes but not overbright result anymore.
File attatched (+ screenshoot were to put) in first posting.
For me submitting result worked. Perhaps some problem like special characters? in name / pwd ? I would use an simple one if it fails.
Never use your main pwds (email & Co) for such cases. So doenst matter if you let it simple.

I could not send results some time ago ("login failed"). But now results submission is working properly.

Nvidia GTX 580 ("MSI Ligtning" oced @915Mhz) = 1230

GREAT ! First place with Single GPU for npwski

http://www.luxrender...op20/Sala/GPU/1

GRATULATIONS :yoji:

PS: Woudl be nice if you add the CPU + GPU result.
i7 860 + 3x ATI 5870 around 2700 in the results cpu+gpu db,
maybe you bet them or came close with only one GTX 580 + same cpu ?
background: The more gpus the faster has an limit - the cpu is the bottleneck in that case.
So 4 5870 are only very little faster than 3 5870 with same cpu. cpu + systembus + PCIe Bus is overloaded by huge datatransfers. GPUs must wait to get their results back to cpu.
To fire lots of such highend gpus fast enough you would need an cpu + systembusspeed + PCIe speed
which isnt developed already ;)

Tested again with the new config.cfg file:

ATI Radeon HD 4830 512MB: 151 (same result with the older cfg file)
ATI Radeon HD 4830 512MB + Intel Core2Duo E6750 oc'd 3,2Ghz: 246

Thank you, Mitch :)
And no, i can't beat "i7-860 + 3x Cypress", because my quad-core CPU not so fast as 3x top-level GPU. Anyway, it's CPU+GPU score:

i7-860 @4100Mhz + single GTX 580 @915Mhz = 1341

219 = GPU only or CPUs + GPU. Other 9800 GT got 88 gpu only.
If gpu+cpus please post gpu only result too.

Incredible:
4 * AMD 7970 GPU only got 6153 (win, http://www.luxrender...etail/result/87 )
I must buy 90 of 9600 GT to get close to that ? ;)
Also you can see that in such case, many highend gpus must be fired fast with data from cpu, it happens that
gpus+cpus is much SLOWER than gpu only. Thats because the cpu is on the limit communicating with the gpus already and if the cpu has do do own work beside that the overall speed getting very worse compared to gpu only.
This chart (from that 4* AMD 7970 hero) shows that drasticly:
Attached File  SLG.BENCH.png   25.98KB   27 downloads

Also the very small improvement from the OS X hero GTX 580 vs GTX 580 + i7 , 1200 vs 1300 shows that already.
cpu is on the limit - already with one fast gpu.

Hi friends, soon there will be an new beta which has added an third scene - complex with more than 2 Mio triangles to compute.
Its unclear if gpus <= 512 MB can compute that (depends on the driver). With > 512 MB VRAM it should be no problem.
EDIT: V2.0Beta2 (with new scene room ) now available at same DL link first posting.
i added new results section room in the first post. I got 23 with gpu only GT 9600 512 MB.
The results DB website also updated. complex = room scene.
NEW: The results DB now has an search function , where you can search with OS type, scene type,.... so you will see your and similar
results even you are not listed in the TOP 20.

Did it again with GPU + CPU

2600K 3,4 GHz + HIS 6870 -> Result 884 points
Exactly 400 more

Dont forget to DL new Beta2 (same DL Link as Beta1, 1. posting) and test new very complex scene room (> 2 million triangles, huge VRAM consumption)
512 MB VRAM is little to less VRAM for good speed, so it will be much speed diff between same gpu with 512 or more MB (640,....).
640 MB VRAM s already enough for that room scene.
