Head-to-Head Benchmarks

The database contains a single benchmark entry for the NVIDIA RTX 5000 Mobile Ada Generation: a 3DMark Steel Nomad DX12 test with a score of 3596. The Intel Arc G3 Extreme has no benchmark entries, and the head-to-head benchmark table between the two is empty. The NVIDIA part's nearest rivals in the database are all older or lower-tier cards: the NVIDIA GeForce GT 545 with an average score of 3594 and a delta of 0.1%, the NVIDIA GeForce GT 735M at 3616 with a delta of -0.6%, the NVIDIA GeForce GTX 1050 at 3629 with a delta of -0.9%, and the AMD Radeon HD 6770 at 3649 with a delta of -1.5%. These figures indicate that the RTX 5000 Mobile Ada Generation's score is tightly clustered with these legacy parts, despite its vastly superior specifications. The Intel Arc G3 Extreme's lack of any recorded benchmark data means the comparison is one-sided: the NVIDIA part delivers measurable performance, while the Intel part's capabilities remain unquantified in this database. The NVIDIA part's FP32 compute of 41.15 TFLOPS is more than five times the Intel part's 7.680 TFLOPS, and its texture rate of 643.0 GTexel/s exceeds the Intel part's 120.0 GTexel/s by a similar margin. The pixel rate gap is also wide, with NVIDIA at 236.9 GPixel/s versus Intel at 60.00 GPixel/s.
