ATI lineup comparison
With speeds of 500MHz on the graphics core and 480MHz for the memory, the clock speeds of ATIís All-In-Wonder X1900 should look awfully familiar to anyone whoís followed ATIís graphics cards: these speeds are nearly identical to the Radeon X1800 XL and All-In-Wonder X1800 XL, which shipped with a 500MHz graphics core and 500MHz memory.
In case you were wondering why 480MHz instead of 500MHz for the All-In-Wonder X1900ís memory, ATI stated that they were shooting for the boardís memory modules to run at an even 500MHz, but had to settle for 480MHz in order for the board to make it to market on time. Itís here where things get a little interesting, as our pre-release engineering sample board shipped with a different cooling unit than the cooler thatís going to be used on shipping, retail All-In-Wonder X1900 cards. For shipping All-In-Wonder X1900 cards, ATI borrows the exact same cooler that was used on Radeon X1800 XL/All-In-Wonder X1800XL boards. In contrast, the heatsink on our board was actually a little bit smaller than the heatsink ATI uses on final All-In-Wonder X1900 cards, but the fan used on our All-In-Wonder X1900 board was larger and runs quieter. Itís because of this that we actually prefer the cooler used on our board, particularly for use on a multimedia card, as youíll want your PC to run as quietly as possible when watching movies/TV on your PC.
(and we stress the word guess) is that ATI couldnít squeeze the extra 20MHz out of the new All-In-Wonder X1900 cooling design, despite the use of a new heatsink/fan unit, so rather than use the smaller cooler they decided to stick with same cooler thatís been used on Radeon X1800 XL and All-In-Wonder X1800 XL cards in the past. After all, ATIís probably got a ton of them lying around since the X1800 series cards are no longer in production. By sticking with the old cooler, it also allowed ATI to get the All-In-Wonder X1900 to market on launch day.
Again, this is all just a guess on our part, but it makes a lot of sense. The 20MHz deficit shouldnít make much of a difference in performance anyway.

Another interesting ďguessĒ we made in our Radeon X1900 article last week is that todayís All-In-Wonder X1900 card may provide a preview of whatís to come with ATIís vanilla Radeon X1900, if such a card were to be announced in the future. Remember, right now ATIís only announced three Radeon X1900 products: the Radeon X1900 XT, Radeon X1900 XT CrossFire, and the Radeon X1900 XTX. As of right now, there is no Radeon X1900 card.
But just as ATI didnít announce a vanilla Radeon 9700 on launch day when R300 was first introduced, only to eventually produce such a part just a few months later, we wouldnít be surprised to see ATI announce a vanilla Radeon X1900 at some point in the near future. After all, now that the Radeon X1800 XL is no longer in production, ATIís got a huge $300+ hole in their product lineup to fill between the Radeon X1600 XT and the Radeon X1900 XT. Because of this, we donít think itís unwise to guess that ATI may eventually want to produce a vanilla X1900 card. And with the All-In-Wonder X1900 sharing similar clock speeds as the All-In-Wonder X1800 XL, we can see exactly just how much of a performance improvement R580ís new 48-shader architecture brings!
