4850@750Mhz vs 4870

[Truckchase!]

Need to be able to compare, so need to choose from the games and settings the reviews use, unless you can find some results from forums with the same game and configuration like I happened to find with the 280gtx result to compare with your very high run.

Truckchase!, a mild overclock shows the difference between GPU and memory, but it's less likely to show where the performance drop off is at, the 4850@750 and 4870@625 allows to compare to any review, and satisfies that whatif itch of a question of medium vs high end card. Also of interest and in the same vain as the medium vs high end whatif is max overclock vs 260/280gtx competition/topdog.

1. What performance drop off? GPU, memory, both? Be specific.
2. You can't compare to a review. They have different base hardware, different OS, different benching techniques, etc. On top of that I can't guarantee the skill of the tester. (nor should you)
3. Max overclock will vary on a card by card basis, but obviously will reach an average. (as I believe you're getting at) However, the point of this thread is not to compare to Nvidia products, but to compare a 4850 vs. A 4870.

My point is that the main difference between a 4850 and 70 is the memory bandwidth. (yes I realize the voltage circuity is better on a 70) Given this information, one can conduct tests to see if the 4850 is memory bandwidth limited and answer the majority 4850 vs. 4870 question, which is the premise of this thread. That being said, I think I'm going to unwrap my 4850 tomorrow and do some tests since I have the automated scripts to do so. The offer still stands if anyone wants to buy this card since I'm getting 70 from FXVideoCards on Wednesday.

Edit: Oh snap, I didn't see that it was you that opened the thread until now KeithS.... do you want to change the context? I can't provide Nvidia data.... I'll just say they're "for the most part, faster and more expensive"
