Haswell GPU vs Dedicated GPU

[rarenick]

When the time comes, if I can get hold of a Haswell cpu which has good graphics performance, will it out-win my current GTX460? I am thinking whether it can replace buying a dedicated card.

On the other hand, if I use dedicated graphics card, it means the GPU on the Haswell will be useless? Or can we run a parallel to both GPUs?

A dedicated GPU has 1 or 2GB RAM these days to load the graphics data. Hence, the GPU on Haswell will use the system RAM? Meaning I have to load my system with more RAM? Instead of 4GB in total, I should pump up to 8GB?

Wayyyyy slower man

It can replace those that are priced at $50~100

On the other hand, if I use dedicated graphics card, it means the GPU on the Haswell will be useless?
Yes

Or can we run a parallel to both GPUs?
No. But you can use the Haswell GPU to do something else. Like video decoding/encoding, or I dunno... rotate 3D objects or something

A dedicated GPU has 1 or 2GB RAM these days to load the graphics data. Hence, the GPU on Haswell will use the system RAM? Meaning I have to load my system with more RAM? Instead of 4GB in total, I should pump up to 8GB?
Yes. Although most games up till now don't use more than 2GB system RAM and way less for video RAM. Things will start changing after programmers stop supporting 32-bit OS.
4GB is too little for a new system today anyway. 8GB min, 16GB better.

thanks for your post. it helped a lot

Can compare a GTX460 with Haswell graphics man... It is a good alternative to say ultra books due to space constraints, but if you are on desktop and you need a good graphic card for games, then you really gonna look elsewhere.

Do note you may have more system ram, but the bandwidth should be significantly smaller than a dedicated graphic card. The bandwidth on the integrated graphic is shared. Amount of memory also does not translate to improvement in performance. Haswell improved by giving the graphic card a fairly big cache, but will not completely solve the lack of bandwidth issue I believe.
