The Radeon HD 4850 & 4870: AMD Wins at $199 and $299

Call of Duty 4
Call of Duty 4 shows the Radeon HD 4870 outperforming the Geforce GTX 260, despite being priced $100 more than AMD's offering. What's interesting is that while at 1920 x 1200 the Radeon HD 4870 is nearly 11% faster than the GTX 260, the two perform the same at 2560 x 1600. It's not a memory bandwidth limitation since the 4870 has tons of it, so it looks like we're running into some sort of a processing power limitation.
The 4870 also nips at the heels of the GeForce GTX 280, but it cannot catch up to the performance offered by two GeForce 8800 GTs in SLI thanks to excellent SLI scaling here. As we've already seen, the Radeon HD 4850 is not only faster than the GeForce 9800 GTX but also the new 55nm GeForce 9800 GTX+.

http://www.techpowerup.com/reviews/Powercolor/HD_4...">http://www.techpowerup.com/reviews/Powercolor/HD_4...Look! Compare the Powercolor vs. the MSI.
Somehow MSI seems to have done a better job with 4dB less.

I thought it was only Johan, and it was sort of understandable since he's not a native English speaker, but it seems most Anandtech writers don't know the difference between "its" and "it's"."It's" means "it is" or "it has" (just as "he's" or "she's"). When you're talking about something that belongs to something else, you use "its" (or "his" / "her").
In a sentence such as "RV770 in all it's [sic] glory.", you're clearly not saying "in all it is glory" or "in all it has glory"; you sare saying "in all the glory that belongs to it". So you should use "its", not "it's".
Even if you can't understand the difference (which seems pretty straightforward, but for some reason confuses some people), modern grammar checkers will pick this up 9 times out of 10.

I am not a native English speaker, but I am well aware of the difference. I am also sure that reviewers are also ... it's just that - with all this text, we can forgive them, can't we?I have a bachelor of computer science, studying for higher degree, but: I look at the technical side of the article, so I don't even notice the errors :D (although I can tell the difference I simply don't see it while reading)

Oh, I forgot: maybe I'm just being too enthusiastic ;)JarredWalton - Wednesday, June 25, 2008 - link
More likely is that with a 10000 word article and four lengthy GPU reviews in two weeks, errors slipped into the text. I know at one point I noticed Derek says "their" instead of "there" as well, and I can assure you that he knows the difference. I know I use Word's grammar checker, but I'm not sure Derek even uses Word sometimes. :)araczynski - Wednesday, June 25, 2008 - link
of the 4850's, slickdeals has posted a sale, between rebate and coupon off...$150 each. can't beat that bang/$ by anything from nvidia.first ati cards that will ever be in my computers since i've started with the voodoo/riva tnt :)

Page 15: first reference to "GTX 280" should be "GTX 260" instead.Page 19: I think you meant "type" not "time" in this paragraph.

This review is flawed. It shows greater than 100% scaling for Crossfire 4870 in Call of Duty 4. Why don't they just give us the raw numbers for both single and dual cards in the same scenario? Why use a method that will artificially inflate the Crossfire results?Denithor - Wednesday, June 25, 2008 - link
If you read the comments before yours, you'd see the answer.Experimental error and/or improved scaling for each card versus a single card. Read the earlier comment for more details.
