Queston for the GODS...

This is a post I replied to at the webpage described below.. .hope you find this info useful and hopefully one of the GODS (or many!) will be able to answer the questions at the end..

Regards!

Great update!! Thanks. (my previous post got LOST!! too bad).

Just wondering if anyone can tell if the 460m with GDDR5 is equivalent to the 285m with GDDR3?

460m = 21,000 M/texels, 16,200 M/pixels, 192 bit, 60 GB/s
285m = 38,400 M/texels, 9,600 M/pixels, 256 bit, 65 GB/s

In order those are:

Texel fill rate
Pixel fill rate
Memory bus width
Memory bandwith

Any SUPER EXPERT or GURU that could know if the 460m would out perform or would be basically the same as the 285m?

The only benchmarks available seem to be at:

NVIDIA GeForce GTX 460M - Notebookcheck.net Tech

Don't know how the texel, pixel, etc., numbers were gathered. Would be interesting to know too.

 

Having you tried looking through the ORB benchmarks?

Hi, thanks!

Didn't try that one before, but I just did and there is only one benchmark for the 285m GTX... and at the end the data is kind of incomplete...



(or maybe I don't know how to search correctly there..)

 

With the basic profile those results are correct, not all the tests are performed but the composite score and the break down for SM 2, 3 & CPU are reliable.

You can also check out passmark benchmarks, then tend to have fairly good data:

The data from the Notebookcheck Benchmark list is useful:

http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html

The data for the 280m is fairly good, although the data for the 460m is sparse, with only two verified results, but it's better than nothing.

They look to be fairly on par with one another by the numbers:

   3DMark05  3DMark06

460m: 18669    12322

280m: 18414    12569

 

Doesnt the DDR3 make the 285 quite significantly slower vs. the DDR5 of the 460?

 

Wouldn't Vantage be a better benchmark to compare these instead of 3DMark05/06?

 

I tend to use 3DMark as a comparison benchmark since most people are more familiar with it compared to Vantage, but you make a good point in that the 3DM05/06 benchmark is getting a bit long in the tooth compared to the current state of the art.

 

3DMark06 is really irrelevant with newer GPU's unless you plan on playing a lot of older games, in either case, then either GPU will suffice. But I understand though, since FutureMark charges to use their product it's a little bit of a turnoff.

 

Memory bandwidth is only important if the GPU has enough throughput to use all of it.
