And faster than a Blizzard 1260 @ 80mhz by quite a margin for write long word :O

& still in beta

FAST looks much better now.

what about CHIP, there a chance for speedup?
that is the bottleneck for good fps.

About firmware update:

https://www.exxoshost.co.uk/forum/vi...hp?f=75&t=4365

in short: (copy and paste from stephens text)

Ok ... so there will at some point be a firmware update to the TF1260. Here is a bit of FAQ...

1. The update will be free (no actual charge for the update at all).
2. The update will either be done physically (i.e. mail your card back to your builder) or if you have a Xilinx programming setup I believe we are looking at doing remote updates over something like teamviewer.
3. You will keep your serial number.
4. If you buy a second hand TF1260 you will not be eligible for the update (this is mainly to prevent people flipping them and price gouging).

At present the plans for the update are

1. PIO-4 Mode ATA on the TF-IDE interface.
2. Burst mode performance.
3. removal of the 14 vs 50Mhz clock switching stunt.... which should allow higher clock speeds overall.

I have at present done 1 and 2 but i have not started 3. Given the pain involved in the update i didnt want to have to do too many of them.

I will also generally release jeds once a particular number of units sold has been passed. we're about half way. Those will not have specific serial numbers.

so test at 62. as it IS beta

Nice numbers indeed!

There’s a photo now on exxos which shows the speeds for 75mhz. They confirm that the TF1260 scales ram speed beautifully. In fact, clock for clock it’s ram speed is equal or better to everything out there at the moment*, including Warp1260, Blizzard 1260 and matze’s own 68060-TK. Obviously these newer cards are still in development too so may change.

(*I leave out the vampire - think that has very rapid ram access but I am not sure what it’s figures are - I think maybe several hundred mb/s?)

[NorthWay]

Erm... I thought Matze's card was doing better, sth like 80M/s?

[DJBase]

Compared to my poor ACA1233n with 40MHz...

It does... there was a small benchmark table somewhere around...

[Mathesar]

I doubt whether those final few megabytes/s for fast ram make a difference in real-world performance.

[Adrian Browne]

How much are these? I did not see them on amibay. Where are they sold?

yeah, but if the TF1260 scales it's memory like the 62 and 75 mhz bustest results show, all the way to 100mhz, then it'll be very similar in speed

So you Tested on a A500 Connected to the ACA500?
Cool , Would try this tooo, just got my TF1260
Anything i have to be aware of?

[johnnybarker]

Yes, I never thought to try it on my 500plus. I'll give that a bash at the weekend if I get a chance.

You have to get kind-of invited to buy one.

Who will invite me to the party!...

no, a cpu can only calculate fast, if it get the data fast.
and half chipramspeed is half framerate.

I was talking about the fast ram. I think that those final few megabytes/s do not make a huge difference. Now, chip ram acces speed is another matter.

[E-Penguin]

No luck here with TF1260 and my aca500plus. It gets as far as the config menu, and recognises the 060 is present, but it does the green screen of death once I try to start it up.

I have a 2mb Agnus (with a mega chip)

If anyone has any tips I'd appreciate it

weeeeelll not really.. as you still can do a C2P in one frame.. so 25FPS as max..

then the rest handles about how much the 060 can do the real actual effects.
