Sapphire Radeon 9250 registers as 9200 under OS4

A friend of mine kindly sold his old Sapphire Radeon 9250 AGP card to me. I installed it into my AmigaOne and it works ok - however, PCIScan reports it as a Radeon 9200!

14 0x1002 0x5C61 ATI Technologies Inc M9+ 5C61 [Radeon Mobility 9200 (AGP)]

Can anyone explain what this means? Is Sapphire 9250 just a modified 9200? I went to Sapphire's web site but could not find any useful information. Search with Google brought a lot of related pages but none of them brought light to this issue.

@GrumpyOldMan

Maybe the chip is the same, but the board has some improvments.. ?

@GrumpyOldMan
Have you checked it with Ranger? what does it say there?

@GrumpyOldMan

9250 and 9200 are essentially the same but the 9200 has a 10Mhz higher clocked core.
The thing you should be concerned about is if your 9250 has a 64 or 128 bit memory controller.

edit.

Does PC scan show the card as an RV280 or RV280LX? The core code for the 9250 has the LX suffix according to info I got.

Most of the cards available here are 128bit. In what way should I be concerned?

6.4 GB/s versus 3.2 GB/s memory bandwidth.

@Swisso

No, I have only used PCIScan - will try out Ranger when I get back home.

@Rob
No idea about the memory controller bus width of the card - I'll try digging out some more info about that.

@GrumpyOldMan

Ranger uses the same pci.ids file to identify cards that PCIScan does.

Here's what I get with PCIScan DETAIL:

Does not reveal much to me at least

@GrumpyOldMan

Radeon 9250 and Radeon 9200 are the same cards, the latter one is a re-release of the original Rv280 chipset with slightly altered parameters (memory/core clock etc). For all intent and purpose, the cards are the same - they have the same vendor and device ID and can only be identified by their subvendor/subdevice ID or the setup in the ROM.

From the programming side of things, any R[v]2xx card is identical anyway (with the exception of the original R200 aka Radeon 8500 aka Radeon 9100 which I never got to work reliably) so there is no problem about a card being listed as Radeon 9200 - the're the same cards anyway.

Hope this helps.

@noelfuller

With 64 bit cards like the 9200 SE or the Radeon 7000, you will notice that 32 bit modes are a good deal slower than 16 bit modes.

@Rogue

Many thanks for the clarification. I bought the card for OS4.1, and hope this means I can use all of its features with this model

@all
One final question - I assume the M9+ is a sort of low power (mobility) version of RV280 - can anyone here clarify whether M9+ uses 64-bit or 128-bit memory controller?

@Rogue

That would really mean that running the micro A1 in 16-bit is probably a better idea.

@GrumpyOldMan

My card sounds identical to yours and mine is 64-bit. I don't know if there is any way to tell directly unless you have the original packaging, and even then, who knows.

@all

Radeon 9250 here too. I have to say, the picture quality (output signal) is definitely better than on both radeon 7500 and the radeon 7000 evethoug the latter ones where new when I bought them and this one is 2nd hand.
And WipeOut2097 flies!!

@xeron
ranger lists my VGA and Display controller as RV280 (Radeon 9200 Pro) but also lists the graphics board as a Radeon 9250
so can I deduce that Ranger is more circumspect than Pciscan?
