Here's my Atari 520STM.
Not quite a TT, but it likes to pretend that it is and who am I to argue
It's equipped with a TF534 accelerator running @ 50Mhz.
4MB TT-RAM on accelerator card.
4MB ST-RAM on mainboard.
I don't have any FPU that can handle 50Mhz so the FPU slot is empty until I find one.
Code: Select all
NemBench v2.1 - precision CPU/FPU profiler.
Integer multiply (16bit) -> 1.921 Mips (~313%)
Integer divide (16bit) -> 1.135 Mips (~313%)
Linear (stalled) integer -> 24.975 Mips (~313%)
Interleaved (piped) integer -> 24.975 Mips (~313%)
16bit read (100% hit) -> 24.630 MByte/sec (~313%)

really impressive figures, just for the record, it should be posted there
Falcon and NemBench .
Here we compare vs TT and Nembech shows figures vs Falcon.

do you have a picture of how you installed the tf534 inside the case ?

Hi czietz,
By the way thank you so much for your lightning VME drivers they're absolutely excellent. Just wondering, do you worry about your TT being overclocked, or are the risks negligible. Thx

Overclocking is limited to CPU, FPU and TT-RAM. CPU and FPU run cool and stable at 48 MHz (extensively tested) and the Storm TT has been optimized to handle that speed. Therefore: no, I don't worry.
