Is PCIE 1.1 a bottleneck for 2.0 GPUs?

BicycleRow · 27 Apr 2017

I guess It probably depends on CPU and other things. My current card is a GT 710 (PCIE x8 2.0 card) and it runs in a PCIE x16 1.1 slot. Is there a big difference? My CPU is a Core Duo E7400 @ 2.80 GHz.

I'm also considering buying a slightly better, but still pretty outdated GPU - the GT 730 (more specifically this one - GT730-2GD5-BRK | Graphics Cards | ASUS Global
) It requires PCIE 2.0, which is twice the bandwidth of a PCIE x16 1.1 slot. Will there be a significant performance difference?

I've ran a GTX 660 on a Core 2 Quad Q6600 on a ASUS P5K Pro, which had PCIe 1.1, and there was not much of a bottleneck. The CPU will be the biggest bottleneck.

You could install a 750 TI and it would be fine. The 710 to 730 would be a GPU bottleneck, but they should run fine.

The 660 is a 3.0 card though

For your review and consideration:

Technically yes but in real terms very very little difference,

It won't make any difference, especially for such low end cards. The biggest limitation in your system is your Core 2 Duo. Upgrading your system with a better GPU is pointless at this point unless you also want to replace that processor with high end Core 2 Quad Q9xxx or QX series which still offer marginal improvements.

I personally still use a GT730 (Kepler variant) and my Core 2 Quad Q8200 is the primary bottleneck in most games.

- you might need to install a bigger PSU to facilitate a hardware upgrade,
- your current PSU won't handle much more load..

You will barely notice the difference. I run Core 2 Quad Q6600 on a GA-P35-S3L with GTX 460 SE.

You will feel the difference when the processor bottlenecks the graphics card or vice versa.

unfortunately, due to motherboard & BIOS limitations, the board that OP (BicycleRow) is using can't use Intel Core 2 Quad processors; system will not boot (no video & no POST) using any Intel quad-core CPUs. He can only use up to maybe an Intel Core 2 Duo E8400, E8500 or E8600 with the latest BIOS update for his board.

I had the MS-7525 that came with my first PC (HP Desktop) and I confirm it can only support up to Core 2 Duo E8600 but not quad-core processors. HP did not offer a bios update to support quad-core CPUs for that motherboard.

G33 and G31 chipset naturally supports quad-cores already but the MS-7525 was released very early that HP did not bother with it. Benicia motherboard which is also G31 supported quad-cores.
