Intel B580 GPU Driver Update Improves Performance on Select Games and CPUs

Recent Intel B580 GPU driver updates deliver selective performance boosts while exposing persistent CPU bottlenecks in gaming benchmarks.

Intel keeps working on its GPU drivers even if Nvidia and other competitors are putting pressure on it. Recent upgrades have fixed some big performance problems, especially on lower-end CPUs.

A close look showed that Intel GPUs have had problems with driver overhead in the past, which slows down performance on lesser CPUs.

The latest B580 drivers try to close this gap and make games that are susceptible to CPU bottlenecks run better overall.

Test System and Methodology

To evaluate the impact of the latest drivers, the Intel B580 GPU was tested in an Amazon-built system featuring a Ryzen 5 5500 CPU, 16GB of DDR4 RAM running at 3200 MHz, and other standard components. This configuration represents a lower-end PC where driver optimizations could make the most noticeable difference.

Previous research has shown that Intel GPUs, when paired with slower CPUs, underperform relative to their competitors. For instance, a comparison between an RX 9060 XT 8GB and the B580 indicates that performance disparities expand on CPUs like the Ryzen 5 5600, while high-end CPUs like the 9800X3D exhibit negligible changes.

Initial Benchmarking Results

Starting with Counter Strike 2 at 1080p low settings, the baseline results with older drivers revealed 180-240fps. CPU and GPU utilization were low, with GPU usage dropping to 30%, which is unusually low even for CS2. Cyberpunk ran at 1080p high settings, producing around 80fps, though GPU utilization only reached 75%.

Doom: The Dark Ages consistently hit 100% GPU utilization, indicating it is not CPU-bound. The Last of Us at 1080p high used over 8GB of video memory but experienced high CPU utilization and noticeable frame time spikes, affecting playability.

Stalker 2 showed about 50fps in dense areas, revealing significant CPU bottlenecks. Moving to 1440p improved GPU utilization and reduced stuttering across games.

Effects of the New Drivers

After installing the updated version 8132 drivers, the results were different for each game. It was unfortunate that Counter Strike 2 didn't get much better. Cyberpunk 1080p had lower 1% lows, but 1440p got rid of the difference. Doom: The Dark Ages stayed the same, as expected, because the GPU was already at its limit.

Interestingly, The Last of Us had less stuttering at 1080p, making the game easier to play overall. The findings at 1440p stayed the same. There were no modifications in performance for Stalker 2, which was disappointing. Testing Spider-Man showed that things had gotten better, just like Mr. Steve said.

However, gains were smaller on the Ryzen 5 5500 due to lower clocks, half the L3 cache, and PCIe Gen3 limitations, which introduced CPU bottlenecks not present in the Ryzen 5 5600.

Intel System Comparison

To further investigate, the B580 was tested in an Intel system using an i5-13400 CPU. Counter Strike 2 showed about 30fps improvement with the new drivers at both 1080p and 1440p, indicating that PCIe Gen4 support may be essential for noticeable gains.

Cyberpunk results remained similar, with minor changes in 1% lows. Stalker 2 performed better overall on the Intel setup, but still did not benefit from the driver updates.

Spider-Man exhibited about a 20% performance uplift at both resolutions, confirming that certain games can take advantage of the new optimizations.

Final Thoughts

The latest driver upgrades have made Intel GPU performance more stable. But the results are different for each game, CPU, and PCIe support.

The B580 isn't always the best card for every game, but it does fare better in some, like Spider-Man and Counter Strike 2, especially on Intel CPUs or PCs that support PCIe Gen4.

Even though there are certain problems, the changes are a step forward for Intel GPU users, making some games more stable and smoother to play.
