Nvidia holds market lead but faces challenges

Nvidia continues to lead in the consumer graphics card market, but its GeForce cards face specific performance issues when paired with certain CPUs. These problems arise from how the drivers manage the CPU workload, which can impact performance in CPU-heavy scenarios.

Performance gaps documented since 2021

The YouTube channel Hardware Unboxed has been tracking these performance differences since 2021. Their tests show that older Nvidia cards, like the RTX 3070 or RTX 3090, can underperform compared to AMD's Radeon RX 5700 XT when paired with older processors, despite the AMD card being less powerful overall.

Modern tests reveal persistent issues

Recent tests by Hardware Unboxed on more than ten modern games showed performance differences in 1080p and 1440p resolutions. These differences were more noticeable in CPU-intensive settings, especially in the 1% Low metric, which measures the slowest frames and highlights fluidity issues.

Performance gaps vary by game and CPU

The performance gap between Nvidia and AMD cards depends on the game and the CPU used. For example, the gap is more significant in Pragmata and nearly non-existent in Spider-Man 2 or Cities: Skylines II. The difference is also less pronounced with higher-end CPUs like the Ryzen 7 9800X3D.

Nvidia's issue is situational, not universal

Nvidia's performance issues are situational and do not disqualify the company from leading the market. Hardware Unboxed notes that the problem occurs in specific games and settings, and that most users do not purchase high-end GPUs to be limited by their CPUs.

Nvidia's drivers and hardware design

Nvidia's GPUs lack a hardware scheduler found in AMD cards, but they use features like the GigaThread Engine and GSP to manage workloads. These components help distribute tasks and reduce CPU load, though they do not eliminate all performance issues.

Intel shows driver improvements are possible

Intel's Arc B580 graphics card initially faced similar performance issues with mid-range CPUs but saw improvements after driver updates. Hardware Unboxed confirmed that driver updates can reduce or eliminate these performance gaps in specific games.
