Where does the first gen Radeon LE fit in the current ATI numbering scheme?

[masterc]

I have noticed all the new radeon cards... 7000, 7200, 7500, 8500
Where exactly does the first gen radeon LE (32meg DDR) fit in this , both with numbering and in terms of performance?

the newer ATI drivers identify it as a 7200 because the Radeon DDR/LE uses the same core as the 7200, however, the DDR/LE uses DDR memeory while ther 7200 used SDRAM.

so, performance wise, the DDR/LE would fit in between the 7200 and the 7500.

Number wise, its just detected as a 7200

The le would fall somewhere around 7100 in its stock form(software crippled core), 7200 with all the GPU features enabled. The numbering scheme doesn't take memory performance into consideration, and there are 7200 cards with DDR Memory (twin heads too), OEMs can mate different memory to the cores, for instance you can get a 7500 with anywhere from 3.6ns to 5.5ns memory. Performance would be very different between the different models but all would still be 7500's.

I terms of overall performance I'd say the Radeon LE in its' stock form would be something like a Radeon 7300. It'll easily cane the 7000 and its' DDR memory should comfortably beat the Radeon 7200.

Since the core of the 7200 is the same as the original Radeon DDR and can be purchased with 64MB DDR memory, I would say it would outperform a radeon Le easily in its stock form and should equall the Radeon 64DDR VIVO with the same memory speed. The original 7200 did come with SDR memory(which are nearly as fast as a DDR Radeon anyway), but 3rdparty's are not held to specific memory configuration. Powercolor has 64 DDR memory model 7200's now.

The official 7200 has SDR memory and I am using this fact when making the comparison. I realise that third parties are free to change what they like.

The original 7200 did come with SDR memory(which are nearly as fast as a DDR Radeon anyway),

IIRC it only had 150 MHz SDR memory which should make it a lot slower than the 166 MHz DDR equipped original Radeon.

True, and an Le came clocked at 148/148 with the core crippled, making it slower than the Radeon SDR prior to tweaking, but.....I'm just pointing out that the numbering scheme relates to ONLY the relative GPU performance, not the actuall performance of the card itself. With a huge amount of third party cards hitting the shelves, you can't assume a particular model is outfitted with particular components or performance level, as you could be making a big mistake(as many have) the key is to look at the GPU rating and perhaps more importantly the amount and type of memory installed (which can be difficult to get a clear answer).

True, and an Le came clocked at 148/148 with the core crippled,

AFAIK the only thing "crippled" about it was Hyper-Z being disabled in Direct3D but a simple software switch would turn it back on. And even with this fact 148 MHz DDR memory is much faster than 150 MHz SDR memory.

The Radeon DDR and Radeon 7200 share the same core. The Radeon Le core < Radeon DDR core, the ATI numbering scheme relates to the GPU core only without regard to the memory, therefore the Radeon Le would place below the 7200 with the ATI numbering scheme in stock form (thats why I gave it a 7100 rating, admittedly I'm just being anal). You can tweak the registry so that it can be equall to the 7200 core, but by definition, it cannot place higher than the 7200 using the ATI numbering scheme.

Example:

FIC 7200 DDR vs Devil Monster 7500 SDR

Which of these is faster? I wouldn't be suprised if the 7200 would be close and perhaps exceed the performance of the 7500 in this case, but it wouldn't change their respective rank with the numbering scheme.

This is excatly; what i was looking for

any new drivers for the radeon le? and where can i get hyper z?
