AMD Radeon R9 370X vs NVIDIA GeForce RTX 4050 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the NVIDIA GeForce RTX 4050 Mobile and the AMD Radeon R9 370X. In the two benchmarks where both devices have recorded scores, the NVIDIA part wins outright. The GeForce RTX 4050 Mobile delivers a Geekbench OpenCL score of 74,748, while the Radeon R9 370X manages 25,893. That is a delta of 188.7% in favor of the NVIDIA adapter. In other words, the RTX 4050 Mobile scores nearly triple the OpenCL result of the older AMD card.

The Vulkan comparison is even more lopsided. The RTX 4050 Mobile posts 75,235 in Geekbench Vulkan, against 9,018 for the R9 370X. The delta reaches 734.3%, meaning the NVIDIA GPU outperforms the AMD GPU by a factor of more than eight in this specific API workload. Such a wide margin reflects not just generational progress but also fundamental architectural changes, which are covered later in this analysis.

Looking at the broader database averages, the RTX 4050 Mobile holds an average benchmark score of 19,049, placing it in the 63rd percentile of all GPUs tracked. The R9 370X averages 15,862, which puts it in the 58th percentile. The absolute difference in average scores is roughly 3,187 points. While the percentile gap appears modest at first glance, the head-to-head results show that the NVIDIA part is dramatically stronger in compute-oriented and modern graphics API tasks.

The nearest rivals for the RTX 4050 Mobile in the database include the AMD Radeon RX 6600 (average score 19,036, delta of 0.1%), the NVIDIA Quadro K6000 (19,030, delta of 0.1%), the NVIDIA Tesla K20m (19,089, delta of -0.2%), and the NVIDIA RTX 2000 Ada Generation (18,954, delta of 0.5%). This means the RTX 4050 Mobile sits in a tight cluster of GPUs, all within a 0.5% band of each other. The R9 370X, by contrast, has nearest rivals that include the AMD Radeon RX 7700 (15,852, delta of 0.1%), the AMD Radeon RX 9060 (16,014, delta of -1%), the AMD Radeon Pro W5500 (15,679, delta of 1.2%), and the NVIDIA GeForce RTX 3060 Ti (16,129, delta of -1.7%). The R9 370X is therefore bracketed by much newer and more powerful parts, which suggests that its score is low relative to modern hardware.

The head-to-head data records two wins for the RTX 4050 Mobile and zero for the R9 370X. There are no tests in the shared set where the AMD card comes out ahead. This is not a close contest by any metric available in the database.

The Verdict

The data is unambiguous. For anyone comparing these two GPUs, the NVIDIA GeForce RTX 4050 Mobile is the superior product in every measured benchmark. It wins the OpenCL test by 188.7% and the Vulkan test by 734.3%. Its average benchmark score is 20% higher than the R9 370X (19,049 versus 15,862). Its percentile ranking is also higher, 63rd versus 58th.

The Radeon R9 370X is an older design. It was released in August 2015, and its production status is listed as end-of-life. The RTX 4050 Mobile is an active product released in January 2023. The generation gap is stark. The RTX 4050 Mobile uses a 5 nm process, while the R9 370X uses 28 nm. The NVIDIA chip, AD107, has 18,900 million transistors on a 159 mm² die. The AMD chip, Trinidad, has 2,800 million transistors on a 212 mm² die. That means the RTX 4050 Mobile packs roughly 6.75 times more transistors into a smaller physical area.

The verdict is straightforward: the RTX 4050 Mobile is the faster GPU in all recorded tests. The R9 370X is not competitive in any shared benchmark. A user choosing between these two based purely on performance data would select the NVIDIA part without hesitation.

Where Each One Wins

The RTX 4050 Mobile wins in every category where both have recorded data. It has a higher OpenCL score (74,748 versus 25,893) and a higher Vulkan score (75,235 versus 9,018). It also has a higher average benchmark score (19,049 versus 15,862). There are no wins for the R9 370X in the head-to-head set.

For the R9 370X, the only recorded benchmarks are Geekbench Metal (12,676), Geekbench OpenCL (25,893), and Geekbench Vulkan (9,018). The Metal score has no counterpart in the RTX 4050 Mobile dataset, so it cannot be compared directly. That is the only area where the R9 370X has any measurement that the NVIDIA part lacks.

The RTX 4050 Mobile also has a much broader benchmark footprint. It has scores for PassMark DirectX 10 (79), DirectX 11 (130), DirectX 12 (61), DirectX 9 (184), G2D (633), G3D (14,423), and GPU Compute (5,947). These tests are not available for the R9 370X, so no comparison can be made. But the existence of these scores suggests the RTX 4050 Mobile is more widely tested and more relevant to modern workloads.

The use-case split is therefore simple. For any workload that relies on OpenCL or Vulkan, the RTX 4050 Mobile is dramatically faster. For older DirectX titles or compute tasks, the RTX 4050 Mobile has recorded scores that indicate reasonable performance, while the R9 370X has no comparable data. The R9 370X is only relevant in scenarios where its specific feature set, such as its 256-bit memory bus or its dual-slot format, might be preferred. But the benchmark data does not support any performance advantage.

Architecture Differences

The two GPUs come from different generations and use entirely different architectures. The NVIDIA GeForce RTX 4050 Mobile is based on the AD107 chip, which uses the Ada Lovelace architecture. The AMD Radeon R9 370X uses the Trinidad chip, which relies on the older GCN 1.0 architecture. This is a fundamental difference in design philosophy.

The manufacturing process is a major separator. The RTX 4050 Mobile is built on a 5 nm process at TSMC, while the R9 370X uses a 28 nm process, also at TSMC. The transistor count reflects this: the AD107 chip contains 18,900 million transistors, while the Trinidad chip contains 2,800 million. The die sizes are 159 mm² for the NVIDIA part and 212 mm² for the AMD part. The transistor density is 118.9 million per mm² for the RTX 4050 Mobile, versus 13.2 million per mm² for the R9 370X.

The memory architecture also differs. The RTX 4050 Mobile has 6 GB of GDDR6 memory on a 96-bit bus, with a bandwidth of 192.0 GB/s. The R9 370X has 2 GB of GDDR5 memory on a 256-bit bus, with a bandwidth of 179.2 GB/s. The NVIDIA part has less bus width but more memory and higher bandwidth.

The compute resources are heavily skewed toward the NVIDIA part. The RTX 4050 Mobile has 2,560 shading units, 80 texture mapping units, 48 ROPs, 20 ray tracing cores, and 80 tensor cores. The R9 370X has 1,280 shading units, 80 TMUs, and 32 ROPs, with no ray tracing or tensor cores. The pixel rate is 84.24 GPixel/s for the NVIDIA part, versus 32.96 GPixel/s for the AMD part. The texture rate is 140.4 GTexel/s versus 82.40 GTexel/s. The FP32 throughput is 8.986 TFLOPS for the RTX 4050 Mobile, versus 2.637 TFLOPS for the R9 370X. The NVIDIA part also supports FP16 at 8.986 TFLOPS (1:1), while the AMD part has no recorded FP16 performance.

API support is another differentiator. The RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The R9 370X supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA part has a higher DirectX feature level and a newer Vulkan version.
