NVIDIA GeForce RTX 4060 Ti to Feature a PCI-Express 4.0 x8 Bus Interface
NVIDIA has traditionally refrained from lowering the PCIe lane counts on its mid-range GPUs, doing so only with its most entry-level SKUs, however, this is about to change with the GeForce RTX 40-series. A VideoCardz report says that the upcoming GeForce RTX 4060 Ti, based on the AD106 silicon, comes with a host interface of PCI-Express 4.0 x8.
While this is still plenty of interface bandwidth for a GPU of this market segment, with bandwidth comparable to that of PCI-Express 3.0 x16, using the RTX 4060 Ti on older platforms, such as 10th Gen Intel Core "Comet Lake," or even much newer processors such as the AMD Ryzen 5700G "Cezanne," would run the GPU at PCI-Express 3.0 x8, as the GPU physically lacks the remaining 8 lanes. The lower PCIe lane count should simplify board design for AIC partners, as it reduces the PCB traces and SMDs associated with each individual PCIe lane. Much like DRAM chip traces, PCIe traces are meticulously designed by EDA software (and later validated), to be of equal length across all lanes, for signal integrity.

If csendesmark's 7900 XT responds similarly then he's seeing a 1-2% reduction, which would "feel" identical. Where is your 50% number coming from?
It's set to launch on the 24th so not much longer to wait for reviews.

I see the same "loss" on this card as for the RTX 4090 (with 24GB),
You lost about 1~2% when switch from gen4 to gen3
BF V has one of the biggest differences of all and this is still marginal:
It's very evident that the goal of the 40-series mainstream cards is to provide the minimum viable upgrade over the previous generation while providing the maximum cuts to manufacturing costs, and therefore profits. Nvidia sure as hell aren't selling them for less :D
But the worse problem is not that it has PCIe 8x, the problem es why?, Why does it have PCIe 8x ?
and the answer is easy, because it's a 4050 with a fake name
Can you please advice which cards have 48 or 96 GB of VRAM :laugh:
