Zajímavý a docela nový benchmark GPUPI Superpi. Kdy vlastně výpočet LUdolfova čísla na XX miliónů destrinných míst počítá dle volby GPU a nebo CPU.
Benchmark stáhnete zde:
https://www.overclockers.at/downloads/G ... %201.2.zip

Eventuálně i potřebný Visual C++ Redistributable Package:
http://www.microsoft.com/en-us/download ... x?id=40784

Někdo může na procesorech Intel mít problém spustit program přes CPU výpočet, potom může pomoci instalace intel OpenCL driver
https://software.intel.com/en-us/articl ... cl-drivers
eventuálně dll knihovna/knihovny, tak nainstalovat MPSS 3.4 release for Microsoft* Windows
https://software.intel.com/en-us/articl ... hive#34n-1

Uvádějte případně jak výkon GPU, tak i výsledek s CPU. Výpočet bude probíhat na 20M míst (přednastaveno).

... s CPU (i5-2500K bez OC) to ani zkoušet nebudu, to je tak na hodinu.

to by musela byť 2500k asik 10x pomalšia ako FX

W8.1Pro

wow...5960x na poli CPU tady nic nedá v tomhle multithread superpičku...To už vidím i dle zahraničí.

Ta grafika takdy drsné skóre

Mna by este zaujímali vysledky gk110 a tej 2500k

2500k odhaduju tak o 2minutky horší jak FX s 8 vlákny. Zajímavý myslím bude i Radeon 290/290x díky výpočetnímu výkonu. To bude zajímavej souboj s 980 (která zas jde excelentně taktovat, viz ta tvá )

> pravěk nezklamal, skoro půl hodiny

tak je to default 3,3GHz
a napr to FX 4,7GHz
daj ho na tých 4,7 a bude to lepšie, tie vlákna tam určite chýbajú
nesklamala ani 290

AllCPU meter mi ukazoval 3600 MHz, takže tipuji že 3300 je základ, při zatížení CPU taktne samo na 3600 (3700)... Na 4700 to nedám, nemám na to chlazení. Měl by to spíš zkusit HEAD, má stejné CPU (snad zatím) a tuším že dal max takt kolem 5200MHz, což by bylo zajímavé sledovat výsledek.

Pokud je toto OT, tak se omlouvám a klidně to smažte...

výhodu budou mít určitě vlákna, takže i7 s HT budou s FX poblíž. Haswell bude myslím i lepší (prý tneprogram má i support FMA, což právě FX či Haswellu pomůže)

HunterGtNet: Tvůj výsledek mi připadá dost slabý. Mě to spočetlo o více než třetinu rychleji. Procesor mám mírně přetaktován - turbo pro všechna jádra 4200 MHz.

tak máš o 700 MHz více než on, to není zanedbatelný rozdíl taktu

Je to o 600 MHz (standardní turbo násobič pro plné vytížení je 36). Ale že by o 17% vyšší frekvence přinesla zlepšení 35% se mi nezdá. Tam se musí promítat i jiné vlivy.

sory jsem mel 32bit verzi spustenou
