i7 920 3.6ghz bottleneck

post #1 of 9
Thread Starter 
so long story short, I have a i7 920 quadcore that can be taken to 3.6ghz with 16GB 1333 CL7 and a spare GTX 970. will the two bottleneck each other?


Actually is i7 920XM and 980M, but I put in desktop parts list so it's easier to understand.

The i7 920 will bottleneck in some games as it's a 1st gen bloomfield, not really great for single-threaded games and a 2nd gen or newer CPU will perform noticeably better in CPU bound games. The GTX 970 however wouldn't really bottleneck the CPU at all.

This is my experience coming from a Intel Core 2 Quad Q6600 > Intel Core i5 750, i7 920 > 3570K > 4690K > 4790K.

even at 3.6 it's still going to bottleneck like hell?

I went from an i7 920 to a 6700k and the 920 bottlenecked my system horribly in CPU bound games. I swapped over the GTX 970. One if the biggest gains I remember was in Heroes of the Storm where it practically doubled my FPS with the new CPU. Another title I saw huge gains in was Assetto Corsa. I could not reliably run full AI with the 920, but now I can easily run a full field of cars with room to spare. However, in GPU heavy titles such as Witcher 3, I saw next to no difference. It really will depend on the game. Any titles with lots of AI or other players will see a benefit. Common genres include RTS, MMO, and racing simulators.

It's all about the IPC (Instructions Per Clock) 2nd gen and higher will have a higher IPC count which helps significantly in CPU bound gamees.

But in multi-core optimized games which I think witcher 3 is not so much.

So yeah 3.6GHz on a i7 920 won't help much or enough in CPU bound games. You are better off upgrading motherboard and CPU to haswell or skylake with ddr4 memory of course.

M15x?

Save the power and put it towards the cpu, faster ram will help a lot.

M15x R1 with 1st gen i7 920XM, which is similar to a desktop i7 920.

I have a GTX980M being repaired atm which will be going into the machine, but I'll have to run stock clock and undervolt.

RAM, ssd, and psu all accounted for

You'd have to get clocking to around 4.4GHz to really start seeing some improvement on 1366 socket. You'll only get there with the 32nm 6 core chips being sold for cheap. I personally prefer the W series vs the X. They have a higher Intel stated CPU Vcore max.

The highest rated CPU for this laptop is the 920XM (which I have) or the 940XM
