Just now I uploaded stream memory bandwith test (stream-5.10-Efika.lha) to morphos-storage.net.
There are two versions, one for Efika onboard RAM and second for Radeon VRAM used as RAM. My Efika results are this:
Efika onboard RAM:
Code:
Function Best Rate MB/s Avg time Min time Max time
Copy: 180.9 0.088929 0.088464 0.089880
Scale: 181.8 0.088492 0.088004 0.089383
Add: 175.1 0.137877 0.137030 0.140027
Triad: 174.6 0.138493 0.137450 0.139582
Efika Radeon VRAM:
Code:
Function Best Rate MB/s Avg time Min time Max time
Copy: 24.9 2.575926 2.574070 2.578246
Scale: 24.8 2.582889 2.579801 2.585409
Add: 26.7 3.597471 3.596363 3.598861
Triad: 26.7 3.597352 3.595877 3.599315
In connection with VRAMSpeed picture above, results is expected.
Radeon VRAM->RAM has some flaws, it is not real virtual memory, so sometimes there are problems if application runs both in RAM and VRAM. But it is really very nice improvement for our Efikas. Many more applications now works. Thanks @morphosdevs.
