Mega ST4, PAK68/3-030 without Fastram, ST-Low PAL 50Hz, Frontier run from Floppy

40Mhz with 32kB L2 Cache: 3095
50Mhz without 32kB L2 Cache: 1504

... I have only 35ns Tag Ram so 40Mhz is the max. For 50Mhz I need 20ns ones.

Atari Mega ST4, EmuTOS 1.1.1, 8MB Alternate Ram, MC68010 8Mhz, boot with nothing in ST-Low PAL 50Hz

frames: 931

Alternate Ram has the same speed as ST Ram 3.7MB. Frontier run from floppy

That's an interesting one, Frank. Implies the 010 is approximately the same as doubling the 68k's frequency.

Odd indeed https://www.exxosforum.co.uk/forum/viewt ... f=42&t=861

I'll see if I can find a 010 CPU when I get back home later..

My ST, PAL, stock (68000 @ 8 MHz) as reference: 882 frames.
... with Storm ST Alt-RAM: 906 frames.
... with Storm ST Alt-RAM and 68010 @ 8 MHz: 934 frames. <= confirms Frank's measurements.

Similar results are visible in CoreMark, too.

Thanks, guys. Recorded these on the github.

Also it implies AltRAM measuring the same throughput as STRAM doesn't quite tell the whole tale.

Mega STE 4MB, 16Mhz 68000 + L2 Cache, Blitter off with +6MB Alternate Ram (MagnumSTE)

frames: 1556

The MagnumSTE works not with the Blitter so it´s switch off

Cool benchmark program!

Here's my Atari 520STM (PAL), with 50Mhz TF536.

Running from TT-Ram: 3073
Running from ST-Ram: 1407

My firmware is not stock though. Its got L1 enabled for Rom and ST-Ram access and I believe the stock one only does that for the onboard sdram.

ST-Ram cache misses are not cheap.. but it still makes an noticeable difference for stuff you can't run in fastram without loosing video (ie; framebuffer ending up in fastram)

Nice! Can you share that firmware please? I'm getting 2940 on a ST536 Rev 5.
