Views on the ATI 4870

[DarthPiggie]

thats fine, i guess it was me who trolled, unimportant anyway.

 

[crosshares]

all is forgiven.

anyways back to the 4870, that juicy 4870 😱

I wonder if Nvidia will have an answer to that, maybe a 9800GX2++

I thought G92 milking was done...apparently not, i think you are right though, this cant be it for 55nm g92, im sure. Its really nice though 2Ghz shaders are finally possible.

Here's to trolling:

Is Tom's going to have an article on the 4870 today or more Nvidia headlines

1. Stop showing synthetic benchmarks as the main or the only criteria when comparing video cards. They are very much useless and don't show how the cards will perform where it matters (games).

sorry it is not synthetic and 4870 driver is not even out yet only cat 8.6 with hot fix for 4k

2. It is pointless to speculate about 4870 because we know very little about the card. Hell, we didn't know number of stream processors on 4850 until first reviews surfaced. All that posts like these accomplish is firing up the fanboys on both sides and that means threads like these end in the toilet rather quickly.

it is all updated and fully listed
check anan or maximum pc or even newegg has the spec

NVidia fanboys should be happy that ATI is back because GTX200 will be the last generation of >$400 cards. If 4870 even touches GTX260, NVidia will cut the prices of the 200 series by 25%. Remember what happened when 8800GTX came out and it had no competition? I do and it wasn't pretty.

4870 out performed nv260 and very close to 280 which it makes the position right in between 260~280
nv260 is $300 now.... they knock the price to match 4870 and some companies are selling nv280 for $450

ATI fanboys should be happy because NVidia waited for ATI to get back up after the merger instead of running them into the ground. What do you think, NVidia people just decided to stop running their 6 month publishing cycle because they are lazy or were unable to come up with a G92 refresh before?

lol whatever..... do even you know what exectly meaning of ati 4k all about?

So why make stupid remarks such as "ATI 4850 kick 9800GTX" when if you spend just 3 minutes looking at benchmarks you will see that 9800GTX is still ahead by little. What 4850 did is decrease the price of the card that was $350 month and a half ago to $199. And we all (end users) be happy about that.

"Bad news for Nvidia as the 280 is just simply too large and complex to make into a dual GPU card... " I am sorry, but how do you know this? Oh wait, you don't. So don't talk trash when you don't know what you are talking about.

do you?

this looks like Intel vs AMD back in like 5 years ago when they were having fun with chip-wars only it is AMD/Intel(Havok) vs Nvidia/ageia(or whatever physics they bought)

Here is what ATI aims at
Make the chip in 55 nano so chip gets smaller, less energy hungry, cheaper to produce.
forget the gddr3 but slap the gddr5 so chip don't need big bus and smaller bus? = cheaper to make.
bottom line of 4870 is bit better than 260 and close to 290 but cost only 45% of the 280

i think 4870 is not the last for 4k line and I'm hoping to see 4890 with gddr5 1gig slaped and atleast 20% OC Cap also there is rumor that 9800gtx2+ will be 55nano but who knows .....

AMD learned something from Intel which is good
here is what max pc thinks about 4870

Just looking at these specs 4870 would be very close to 260gtx. 260gtx is really a good match for 4870. It's bandwidth is very similar and spec wise it kind of balances out. Bilinear fillrate is what you consider low quality fillrate for older games but FP 16 blending fillrate is what you would call higher quality for use with HDR. The games today have a bit of both so expect 260gtx to have higher performance in older games and higher max fps but I expect 4870 to have higher performance in newer games and better minimum frame rate and even surpass 280gtx in games like GRID that consist of HDR in the entire game.. Pixel fillrate is very helpful in higher resolutions and AA but RV770 has much better AA performance than Nvidia this time around not to mention more efficient with their ROP as witnessed by 4850 that has higher color fill than 9800gtx with less bandwidth. We weren't that shader limited in the first place. shader help but the biggest gains are usually scene by fillrate.

Excuse my previous post. I had thought RV770 had more filtering ability than previous post. I just assumed this because RV670 had same address and filtering rates and in synthetic test 4850 had higher FP16 blending filter rate than 260gtx before the final specs have been released.

Radeon HD 4870
12.0 pixel fillrate
30.0 bilinear fillrate
15.0 FP 16 Fillrate

This is correct specs but my original post isn't too far off from my speculations.

RV770 is just that much more efficient than GT200 considering it has less filtering rates but able to surpass GT200 far as FP16 blending filter rate goes and easily surpassing pixel fillrate of 260gtx with less ROP.

My previous post about my speculations about GT200 texture to SP ratio have also been mentioned in Techreport pod cast and how it would be able to achieve better performance with GT200. http://techreport.com/articles.x/15103
