PCI-E Scaling


Looking at the performance data generated by this review I suspect that even at PCIe 4.0 x4 there's a significant performance loss for the RX 6500 XT. My estimate would be around 6-10%, which isn't huge, especially in this segment, but it's still performance that could have been easily be achieved for a minimal cost increase. If the cost difference was substantial, everybody would have slimmed down their PCIe interfaces for a long time.

Averaged over our game test suite, we found a 13% loss in performance when switching from the PCIe 4.0 interface to PCIe 3.0. This will happen to you when running the Radeon RX 6500 XT on an Intel platform that's older than Rocket Lake (10th generation and older). On the AMD side PCIe 3.0 is the fastest option when using first generation Zen processors, or when using lower-end motherboards with cheaper chipsets.

I also ran a full batch of tests for the RX 6500 XT operating at PCI-Express 2.0 mode, which is a fairly unlikely scenario. I doubt there's still PCs used for serious gaming with that bus speed. It's still an interesting data point for science. Here the performance loss is another 21% vs PCIe 3.0, and 34% in total when compared against the PCI-Express 4.0 baseline.

Tbh what does everyone else expect in 2022 for £180, It's priced the same as USED RX 570, - yes it's not the best card, but for £180, this is a god send, comes with warranty and longer driver support.

Some things are pretty unforgiveable to be fair. Needing a PCI-E 4 board so you're not losing a significant chunk of performance seems a really odd decision.

Exactly this imo - I'm not sure what people to expect - should people on a budget just not buy a graphics card? or I suppose £200 5 year old ex-mining RX570's are what are recommended?

I appreciate the reviews are comparing apples=apples, but ultra quality settings for everything are never going to be a realistic option for a 4GB card

I'm sure e.g. the AC: Valhalla 60fps 1080P is probably easily achievable by dropping a couple of settings or using the Auto configure options that most games have these days

People who need this and aren't biting at £180 are going to end up kicking themselves later, same as what happened with the 6600/XTs. In my neck of the woods they've been put up for 360 euros!! :eek:

If you have pcie4.0 it's not *that* bad but I feel most people that will buy these won't...very pleased with the 6600 I got from the b Grade section now:p

People also happily buying gtx 1650s for £150+ second hand so again not bad on that front for a new product with warranty as someone else stated.
