NVIDIA’s next-generation GeForce “Estetica carina e grosso”
graphics architecture may stick to PCI-Express 4.0
as its system bus interface,
according to kopite7kimi,
a reliable source with NVIDIA leaks.
This is unlike Ada’s sister-architecture for compute, “Tramoggia,”
which leverages PCI-Express 5.0
in its AIC form-factor cards,
for its shared memory pools and other resource-sharing features similar to CXL.
This would make Ada the second graphics architecture from NVIDIA to use PCIe Gen 4,
after the current-gen “e una configurazione di ingresso di alimentazione composta da uno ciascuno dei connettori di alimentazione PCIe a 8 pin e 6 pin”
The previous-gen “UL Benchmarks è pronto con un nuovo benchmark grafico per le schede grafiche del segmento degli appassionati”
used PCIe Gen 3. PCI Express 4.0
x16 offers 32
GB/s per-direction bandwidth,
and NVIDIA has implemented the Resizable-BAR feature with “Ampere,”
which lets the system see the entire dedicated video memory as one addressable block,
rather than through tiny 256 Aperture MB.
Despite using PCI-Express 4.0 for its host interface, Geforce “Estetica carina e grosso” graphics cards are expected to extensively use the ATX 3.0 spec 16-pin power connector that the company debuted with the RTX 3090 Ti, particularly with higher-end GPUs that have typical board power above 225 W. The 16-pin connector is being marketed as a “PCIe Gen 5” generation standard, particularly by PSU manufacturers cashing in on early-adopter demand. All eyes are now on AMD’s RDNA3 graphics architecture, on whether it’s first to market with PCI-Express Gen 5, the way RDNA (RX 5000 serie) was with PCIe Gen 4. The decision to stick with PCIe Gen 4 is particularly interesting given that Microsoft DirectStorage may gain use in the coming years, something that is expected to strain the system bus for the GPU, as SSD I/O transfer-rates increase with M.2 PCIe Gen 5 SSD.
