which laptop to choose between ...

by raoulos Jul 2, 2013 7:21AM PDT

I will soon buy a new laptop and I was wondering what to choose between two models (which one is the best to game with maximum fps). first choice: 1600ghz 24gb ram, dual radeon 8970m in crossfire and i7-4900mq processor (2.8ghz). second choice: 1600ghz 16gb ram, dual gtx 780m in SLI and i7-4700mq processor (2.4GHz)?
I know that one gtx780m is approximately 20% better than a radeon 8970m but I dont know the difference in crossfire and SLI and I dont know if the processor make a big difference. Which one is the best gaming laptop?

thanks

I see, so the processor does not change much about gaming performance, I also recently learned that the difference is mostly saw in the multi tasking for multimedia (video) and sometimes for 3D rendering. so basically I'm better now to go with the gtx 780 SLI ... (and I know that a desktop is more powerful than a laptop , I chose laptop because I'm nomad ). thank you very much for answering me!

p.s. sorry for the quality of my english, I speak french.)

ehh... I have an other question.

I watched some benchmark video of graphic card and recently I saw something disturbing: https://www.youtube.com/watch?v=mQplgIC_uyw (radeon crossfire 7970M (laptop)) and https://www. youtube.com / watch? v = 6CUtKS7KPHU (gtx 780 SLI (desktop)) yet both have similar scores. I do not understand, yet the 7970M is supposed to be really worse than gtx 780 desktop! already the 780m(laptop version) is supposed to be 30% more efficient than a 7970M amd... I'am lost...

Actually this is why we don't pick by the GPU alone.

In laptops you as the designer can only dissipate so many Watts so to get the sale you may select what sounds like a high end GPU (7970m) and then because you can't pull 100 Watts or dump that much heat you clock down to where it will work given the power and heat limits.

Nothing new going on here and again why you don't pick this by chip alone.

Did you notice they were using Beta drivers?

All bets are off. Get a laptop in your sights, then go get benchmarks for that machine at the places noted.

And it's going to be very rough to get same as a desktop gtx780. In fact I'm going to reverse my statement above about the i5 and i7. In your case you want the last FPS. So a nice new haswell i7 for you.

Odd way to go about this.

by r. proffitt Forum moderator Jul 3, 2013 2:28AM PDT

Try this instead. Pick out a make and model with the setup you noted and see if notebookcheck or CNET did a review with the usual games and frame rates.

I can guess someone new to PCs might think they could pick a winner by picking a CPU+GPU setup but after awhile they'd learn they really want to test the entire package.

As to the CPU, it's only a part of the frame rate for most games today. And laptops still are second behind desktops in gaming. I'm sure you've read the following:

"Our tests demonstrate fairly little difference between a $225 LGA 1155 Core i5-2500K and a $1000 LGA 2011 Core i7-3960X, even when three-way graphics card configurations are involved. It turns out that memory bandwidth and PCIe throughput don't hold back the performance of existing Sandy Bridge-based machines. "
