Nvidia intros PCIe Resizable BAR: Smart Access Memory for GeForce

Graphics, News | | Jan Olšan

With Radeon RX 6000 GPUs and Ryzen 5000 CPUs, AMD unveiled the Smart Access Memory feature, which improves GPU performance by giving the CPU access to whole graphic memory. It was touted as an exclusive feature for these products, but it won’t be in the end. Nvidia has now announced PCIe Resizable BAR, essentialy the same feature, and it’s soon going to be supported by GeForce RTX 3060. Older cards will need a BIOS updat, though.

Next-gen Nvidia GeForce GPU is Lovelace on 5 nm. Up to 144 SMs?

Graphics, News | | Jan Olšan

A year ago, even before Nvidia’s announcement of Ampere, it was leaked that the followup to the current generation is likely called Hopper. But it looks like there may have been a change of plan. According to current leaks, Nvidia is readjusting GPU roadmaps and instead of Hopper chips, the next generation could be called Lovelace. These GPUs are said to already be 5nm and the increase in performance could be very large. Read more “Next-gen Nvidia GeForce GPU is Lovelace on 5 nm. Up to 144 SMs?” »

Nvidia cooking new Ampere card with 7424 shaders, 10 GB GDDR6X

Graphics, News | | Jan Olšan

This week, attention is focused on the unveiling of AMD Radeon RX 6000 graphics, which took place this Wednesday. But Nvidia is already preparing an answer to that. The company reportedly plans to offer another GeForce RTX 3000 model, which will be based on the most powerful Ampere chip, the GA102 GPU. The resulting card should have performance (and price) between the RTX 3080 and RTX 3070 while retaining 10GB of GDDR6X memory.

Some RTX 3080 cards reported unstable. Driver fix lowers boost

Graphics, News | | Jan Olšan

It looks like the release of Nvidia GeForce RTX 3000 “Ampere” will not be amongst those GPU launches that were free of initial issues at the start. Last week, first owners of GeForce RTX 3080 cards began to report instability of the cards allegedly associated with the GPU Boost. The problems might be due to the capacitors used, but Nvidia also solves them by updating the drivers which could probably affect performance. Read more “Some RTX 3080 cards reported unstable.

Cooling, Extra tests, Graphics | | Ľubomír Samák

Graphics card can significantly contribute to cooling of SSD that are installed next to it. However, there’s a very thin line between helping and limiting. Let’s see when your graphics card can be a saviour for your SSD and when it’s an oppressor. As a bonus, we compared the cooling performance with and without the criticised MSI M.2 shield.
