MSI is the newest producer to declare full support for its Z490 motherboard lineup of Intel’s 11th Gen Rocket Lake CPUs. MSI also posted its internal performance numbers with us in addition to the BIOS support, showing resizable-BAR allowed on Intel’s Z490 platform, and also shared a formal release schedule for the AGESA 220.127.116.11 BIOS firmware for motherboards of the AMD 500 & 400 series.
MSI On Intel 11th Gen Rocket Lake CPUs
The first and most notable announcement made today by MSI is the 11th Gen Intel Rocket Lake Desktop CPU support revealed on its Z490 motherboards. MSI now ships with the latest BIOS with its entire top-to-bottom Z490 motherboard lineup, which provides access to the following entirely innovative features:
- Update ME 14.1
- To increase the performance of GPU, support Re-size BAR function
- BIOS updated to be compatible with 11th Gen Intel Core Processors
MSI has also communicated with others its own internal performance testing for resizable-BAR on the Intel Z490 framework in the latest BIOS release. In the simulations, MSI used its MEG Z490 GODLIKE board and fitted this with an AMD Radeon RX 6800 XT graphics card and an Intel Core i9-10900K CPU.
The output metrics are in percentage values and it provides up to 14 percent change and you’ll see where BAR works. There have been certainly a lack of efficiency in other titles, but it is also within the error margin. Enabling the resizable BAR feature provides an average gain of 2.5 percent from all the benchmarks achieved. That might not seem like much, however, in a couple of names, you can get some big uplifts again.
For its Z490 motherboards with current AMD Radeon RX 6000 series and NVIDIA GeForce RTX 30 series graphics cards, MSI has also reported total PCIe Gen 4.0 compliance. As previously published, MSI motherboards also fully support resizable BARs with NVIDIA GeForce RTX 30 series GPUs, but NVIDIA requires a final driver to offer performance uplifts.
As per our information, the justification why NVIDIA is taking longer than expected to work on the drivers is that the graphics cards have to be flashed to allow BAR support. On graphics cards, the vBIOS flash method is relatively riskier than motherboards and only a selection of graphics cards from the RTX 30 series provide dual-BIOS service. With that in view, NVIDIA is developing an ability to increase driver support and bypass BIOS flashing, which on Ampere graphics cards takes BAR support longer than normal.
