I was just checking the new haswell vs Sandy efficiency just for fun.
I happend to have a old Sandy 2500K, been running that chip 4,7-4,8ghz for ever it seems, so i knida know that one well.
Note that the memory is not at the same speed,I will test at same memory speed tomorrow for a better and moore accurate comparison between those two (G3258 and 2500K)
Testing is only singlecore apps,mostly superpi and pifast, anything else is a no-go cause the lack of AES and AVX instructions on the Pentium.(and because it only has two cores of course..lol)
So heres what i discovered about pi today, same speed 4700mhz the Sandy crushed the newer Haswell in superpi1M. (memoryspeed and timings,I know) its Haswell@2133Mhz(2T) vs Sandy@1866Mhz(1T) (slighter better timings too)
The time for Haswell is on page 84-85 I guess, i posted a pic on superpi1M, timefor Haswell was 8.018s and for Sandy and its 7.941s.
I havent done under 8sec on the Pentium yet,need tweak subtimings in bios. But the Sandys timings is NOT optimised either,just fast settings i know will work.
Stupid me,closed the pi-window after a 32Mrun so no pics,but the story is the same there,pics tomorrow after testing.
Heres Pic of my 2500K@4700Mhz@spi1M
Cooling for Sandy
Anybody else done any comparison? Please share..thanks
