Seems like sse1 is useless in such cases , so SD x87 version for amd and SD sse2 for intell wud be enough

Seems like sse1 is useless in such cases , so SD x87 version for amd and SD sse2 for intell wud be enough

So next revision of SkyBoost will be split, one for AMD and one for Intel?

Edit: here are my results for AMD Phenom II x4 @ 4 Ghz

Alexander, i suggest moving the "testing" line down

heres my results anyhow

I dont know much about all this, but it seems most AMD users are getting lower numbers in SSE1 does that means SSE1 is faster? and SSE3 seems to be faster than SSE2 slightly.

There is no SSE3 test amongst them

the tests are

1. x87 FPU (pre SSE)
2. SSE1
3. SSE2.

x87 is apparently fastest on amd (heh, maybe intel wasn't wrong with its ICC "optimisations"

Here's my results from a fresh restart:

CPU: Intel Core 2 Quad Q8200 @ 3.33Ghz (1904Mhz FSB)

Nice overlock, man!

I don't now if any more data is necessary (especially as it's not much different from above cpu), but as someone said 'for science!':

CPU: Intel Core 2 Quad Q8300 @ 3.0Ghz, FSB @ 1600Mhz

Specs in the sig STOCK settings while playing music and uploading a youtube video not to mention numerous other things running in the background.... so i'd say somewhat the average ~> worst case senario right?

Notebook i7-2620M @ default 2.70 GHz

Because of Optimus tech I switched GPU usage for the three test programs in Nvidia's control panel between internal and discreet, but results were basically the same. Ran three rounds for each GPU:

(Intel HD Graphics 3000)
--_x87_----_sse1_----_sse2_--
2121 ms | 2247 ms | 2106 ms
2184 ms | 2199 ms | 2075 ms
2122 ms | 2215 ms | 2090 ms
----------------------------------
(NVidia - NVS 4200M - GF119 - roughly a GT 520M)
--_x87_----_sse1_----_sse2_--
2121 ms | 2184 ms | 2074 ms
2152 ms | 2231 ms | 2075 ms
2137 ms | 2216 ms | 2075 ms

LinUser, its purely a CPU test, gpu's won't have any impact, your variance is just standard variation
