[NHW] RV740 has 640SPs, 32TMUs and cost less than $100?

A number of stories have appeared, based on information leaked from among others CJ, that states that the new RV740 is not the successor of RV730, but more like a shrink of the RV770LE core used with Radeon HD 4830. This core sports 640 shader processors, 32TMUs and 16 ROPs. The memory interface is limited to 128-bit though, but thanks to GDDR5 the bandwidth should remain sufficient.

The 128-bit design and 40nm process all in all should enable a low-cost design and the suggested price tag of around $100 looks quite feasible right now as launching a fast mid-range card would fit in to the limited budgets most people have right now. Theoretic performance should be in the Radeon HD 4850 area, while we can't be entirely certain what the actual performance will be like.

Yay for a Lanbox card for me.

Nice... this might be tempting me. A $100 card that's ~ to a 4850? AMD comin' through with the cost savings.

No because it still less SP and its only 128bit even though its GDDR5

Do you really think that 4850 can utilize all 800SPs with it's mem. bandwidth?

128bit GDDR5 = 256bit GDDR3. Also, the clockspeed increase 40nm process should allow should make up for the lower number of SPs, so I would think this will pretty much match the 4850 (the 4850 will probably win but I think this is going to be marginal).

Yes, because core clock doesn't matter at all.
