Radeon HD 6490M Review
Radeon HD 6490M is an entry-level GPU based on the 40nm Terrascale 2 architecture.
It's based on the Caicos Core (therefore related to Radeon HD 6450) and offers 160 Shader Processing Units, 8 TMUs and 4 ROPs on a 64-bit memory interface of fast GDDR5. Its central clock runs at up to 750MHz (800MHz if paired with DDR3) and the memory clock operates at 800MHz.
Despite being higher clocked than desktop Radeon HD 6450, it's expected to offer the same performance due to lower driver support.
Using a 720p resolution, almost all of today's games are only playable at low settings but with very fluent frame rates (40+).

Note 1: Radeon HD 6490M was later (2012) renamed and released as Radeon HD 7470M.
Note 2: There is also a DDR3 version of this card that has even lower bandwidth but comes higher clocked. Still, it's expected to perform considerably worse.

I ran it on high settings and got like 25-30 fps so it should run fine:) 30 fps is the max you can get on nfs the run.

I'm hoping someone can help with this... I've been trying to run two external monitors simultaneously with my laptop which has this graphics card. I've looked online and seen that this card is compatible with eyefinity, but I can't find this function anywhere in the CCC and I don't know of any other way to run two extra monitors at once.
Has anyone found a solution for this or is it just not possible with this card?

First, can you expand your desktop to multiple monitors via monitor's Properties? (Personalize -> Display -> Change display settings)

Doing that only allows me to expand to one extra monitor, it will show I have two extra monitors connected, but will only let me run one of them.
One is connected via VGA and the other is via HDMI
Tero
10:18 Mar-31-2012

Hmmm, so the monitors are recognized by Windows so that's not the issue... I really haven't used Eyefinity so I'm not an expert at the subject. Found this on notebookcheck.net: "Thanks to Eyefinity the graphics chip is able to theoretically drive up to 4 monitors simultaneously. However, this only works if the laptop features enough DisplayPort outputs." SO maybe that's the issue?

Yea that bit on notebookcheck.net is the reason why I thought I could run more than one external monitor. I've done a bit of digging, and it looks like graphics cards limit the number of monitors that can be used, thats why you need programs like "eyefinity" to increase that number.
I'm thinking that because my computer uses switchable graphics that maybe the integrated GFX is having something to do with it.
Switchable graphics systems aren't fully recognized as AMD systems for some reason and therefore dont have full functionality

@noelj29

 

This is a very strange problem. The only thing I can suggest is going into the game file in the system directory and try installing the direct X file found in there manually.

Okay it seems this is the 512MB GDDR5 version, which means there is no difference between this one and the one with 1GB GDDR5 in terms of performance.
