V5250 Vs. V5200

[RonRonRon232]

On a T60P, which one is better? how do they compare?

[Pascal_TTH]

It's an ATI/AMD *BS* marketing. The FireGL V5200 is based on the Mobility Radeon X1600 and the second on the Mobility Radeon X1700. The only difference between the X1600 and the X1700 is the maximum validated GPU clock speed.

ATI already do the same marketing with Mobility Radeon 9600 and 9700. Exactly the same chips ! Some manufacturers clock the Radeon 9600 higher then other their 9700.


Even ATI have no clear datas on the customer website to make any difference between Mobility X1600 and X1700 except some *features* like Avivo™ enhanced HD-DVD/H.264 . They even don't tell about Mobility FireGL V5250... They also sold a *new* Mobility Radeon X2500 is a renamed X1600 / X1700 chip !

In their nice marketing, ATI also rename Mobility Radeon X1350 as Mobility Radeon X2300.

If you look at performances like fillrate in single or dualtexturing or even at transistors count, number of shader pipelines,number of vertex engines and you will find the truth...

If you look at 3D Mark score, you will notice some better score for FireGL V5250 but it's only because V5250 is used with Core 2 Duo and FireGL V5200 *only* with Core Duo. If you upgrade a T60p with FireGL V5200 from Core Duo to Core 2 Duo, you reach the same score.

That's what found after reading all over the net and with some personnal testings.


PS : Note that notebookcheck also makes big mistakes ! They tell about 24 Pixel-pipelines and 8 vertex-pipelines for Mobility X1700 while ATI writes on their website :
Twelve pixel shader processors
Five vertex shader processors

A note related to your question: some people have reported that they can connect a 30" 2560x1600 monitor to a docked T60p with a 5200. However, none with a 5250 have reported success doing this.

That would mean that the T60p's implementation of the 5200 allows for Dual-link DVI, while the implementation of the 5250 does not. Both chips can handle dual-link, but not both thinkpads.
