I continue here with discussion about VRAM as SlowRAM from
2025 - your expectations:
I tested Efika + Radeon 9200 Pro/128MB with this Radeon tooltypes:
MEM_LIMIT=32
MEM_SPARE2SYS=YES
avail result> Code:
Type Available In-Use Maximum Largest
fast 158.6M 39.9M 198.4M 95.9M
total 158.6M 39.9M 198.4M 95.9M
It works nice, as Amihaharry2 said, OWB works ( some flaws with requesters ). Just now I downloaded via OWB new Morphos.iso. Wayfarer also works.
Of course, it is slow. I tested my read and write speeds to VRAM:
( of course, I don´t know, if this Radeon feature uses the same routines like GfxBench ).
VRAMSpeed-R9200Pro.jpgWrite 71 MB/s is impressive. Read is slow, 18-21 MB/s, but it is normal graphics card behaviour.
And generally, it is near maximum between efika input/output possibilities:
TCP stack: 7.3 MB/s, ATA PIO real: 5.1 MB/s, linux ATA DMA assisted PIO ( theoretical, not tested ) <33 MB/s, linux SATA SiI 3114 87 MB/s ( not tested by me ).
I will test also other graphics cards, if there is difference with read speed. Maybe I have somewhere FireGL 8800.
Quick tests - Quake III now playable, but timedemo freezes. Tower57 works with 16 FPS!
