Again, you are missing the point I made above.  TDP for an HD 7950 is 180 watts.  TDP for the X1800 XL the Xenos is based on was 60 watts. 

The X1800 XL was also very mid range.    It would be comporable to the HD 7750 of today.

not really sure about that but i believe i always read the equivalent to 360's gpu was the X1800 XT and few parts of 1900? (but i really don't know just what i read few times)

btw the xl came out for 449€ and the xt for 549€ here end of 2005. not speaking about wattage and only about the price, people who think a card costing 500€ atm (like the gtx 680) would mean a console would cost above 1000€ end of 2013 should realize how expensive the cards were in 2005 as xbox 360 came out.

Look at the specs for the XL and Xenos again.  They match up much closer than does the XT.   The other architecture it incoproated was from the R600 series (HD 2xxx) by way of the unified shader.

As for price, you'll notice I don't touch on price in my debate.  Only the TDP.

XL and XT had the same GPU chip, only clocked at different speed... xenos had 9 times more MOperations/s processing power than the XL/XT chip due to the addition of extra processing units... it had a higher clock speed (700 against the 500 of the XL or the 625 of the XT) the TDP was almost for sure around 100 watt because of those modifications. XT had a 105 watt TDP.

if the 7850 has a 130 watt TDP that could be the base for Orbis GPU as well... but my guess is still a Tahiti based GPU.

we will see soon enough!

Sergio, the Xenos is clocked at 500 Mhz...just like the X1800 XL.  The Xenos has a 700 Mhz memory clock which might be waht you are thinking of but that's actually a downclock from the XL's 1,000 Mhz memorcy clock.

And expecting any console to launch with the 250 watt is nuts.   10 year life span....not at 250 watts you don't.
