AMD Radeon R5 M430 vs NVIDIA GeForce RTX 4070 GDDR6 Comparison

# The Verdict

The AMD Radeon R5 M430 and NVIDIA GeForce RTX 4070 GDDR6 occupy entirely different tiers of the graphics hardware landscape. The recorded data shows a decisive split: the R5 M430 is an end-of-life integrated-class part built on GCN 1.0, while the RTX 4070 GDDR6 is a dual-slot discrete GPU from the Ada Lovelace generation. Benchmark results indicate the RTX 4070 GDDR6 is in a different performance universe, yet the database places both near the 25th to 30th percentile among all GPUs, a reminder that percentile rankings depend on the distribution of tested samples.

For users seeking modern gaming capabilities, ray tracing, and high-bandwidth memory, the RTX 4070 GDDR6 is the only rational choice from the data. It delivers 29.15 TFLOPS of FP32 compute, 480.0 GB/s of memory bandwidth, and 46 ray tracing cores. The R5 M430, by contrast, offers 547.2 GFLOPS and 16.00 GB/s of bandwidth, making it suitable only for basic display output and legacy workloads. The architecture gap is generational: 28 nm versus 5 nm, 690 million transistors versus 35,800 million, and a 64-bit DDR3 interface versus a 192-bit GDDR6 interface.

However, the nearest rival data for each card tells a curious story. The R5 M430's average benchmark score of 5018 places it within 0.9% of the AMD FirePro W4170M, the AMD Radeon R7 Graphics, the NVIDIA Quadro 4000, and the AMD Radeon R7 M340. The RTX 4070 GDDR6's average score of 4335 sits within 1.2% of the Intel Iris Pro Graphics 5200, the AMD FirePro W2100, the NVIDIA GeForce 930M, and the NVIDIA GeForce GTX 460M. These rival clusters indicate that the database's average scores are drawn from different benchmark suites, not that the two cards are comparable. The R5 M430 was tested with Geekbench OpenCL and Vulkan, while the RTX 4070 GDDR6 was tested with 3DMark Steel Nomad DX12.

The practical verdict: the RTX 4070 GDDR6 is for gaming, content creation, and any workload that demands modern API support and high throughput. The R5 M430 is for legacy systems where the GPU is integrated into the platform and only light 2D or media tasks are expected. The launch MSRP of the RTX 4070 GDDR6 is 599 USD, a figure the database records without any further pricing commentary.

Architecture Differences

The two GPUs share no architectural lineage. The R5 M430 uses the Jet chip built on GCN 1.0, a 28 nm design from TSMC with 690 million transistors on a 56 mm² die. The transistor density is 12.3 million per square millimeter. The RTX 4070 GDDR6 uses the AD104 chip built on Ada Lovelace, a 5 nm design also from TSMC, with 35,800 million transistors on a 294 mm² die, achieving 121.8 million transistors per square millimeter. The density difference is nearly tenfold, reflecting the process node gap.

The R5 M430 has 320 shading units, 20 texture mapping units, and 8 render output units. It has no ray tracing cores and no tensor cores. The RTX 4070 GDDR6 has 5888 shading units, 184 TMUs, 64 ROPs, 46 ray tracing cores, and 184 tensor cores. The compute capabilities diverge sharply: the R5 M430 delivers 547.2 GFLOPS of FP32, while the RTX 4070 GDDR6 delivers 29.15 TFLOPS, a 53-fold difference. The RTX 4070 GDDR6 also provides FP16 at a 1:1 ratio with FP32, while the R5 M430 has no recorded FP16 rate.

Memory architecture is fundamentally different. The R5 M430 uses 4 GB of DDR3 on a 64-bit bus, yielding 16.00 GB/s of bandwidth. The RTX 4070 GDDR6 uses 12 GB of GDDR6 on a 192-bit bus, yielding 480.0 GB/s. The memory clock rates are 1000 MHz (2 Gbps effective) for the R5 M430 versus 2500 MHz (20 Gbps effective) for the RTX 4070 GDDR6.

API support separates the generations. The R5 M430 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The RTX 4070 GDDR6 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4070 GDDR6 also has a PCIe 4.0 x16 interface versus PCIe 3.0 x8 on the R5 M430. Display outputs differ: the R5 M430 is marked "Portable Device Dependent," while the RTX 4070 GDDR6 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The R5 M430 is an IGP (integrated graphics processor) with no power connector, no TDP recorded, and no dimensions. The RTX 4070 GDDR6 is a dual-slot card measuring 240 mm by 110 mm by 40 mm, with a 200 W TDP, a single 16-pin power connector, and a suggested 550 W power supply.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty in the database, meaning no direct comparison test was run between these two GPUs. Each card has its own separate benchmark records.

The R5 M430 was tested with Geekbench OpenCL, scoring 5152, and Geekbench Vulkan, scoring 4884. Its average benchmark score is 5018. The RTX 4070 GDDR6 was tested with 3DMark Steel Nomad DX12, scoring 4334.5, with an average benchmark score of 4335.

These scores cannot be compared as like-for-like because they use different workloads. However, the database's percentile rankings show the R5 M430 at the 30th percentile and the RTX 4070 GDDR6 at the 25th percentile among all GPUs. That both cards sit near the same percentile is a function of the benchmark distribution, not a sign of equivalent performance.

The nearest rival data reinforces the interpretation. The R5 M430's rivals are the AMD FirePro W4170M (average score 5034, 0.3% higher), the AMD Radeon R7 Graphics (4998, 0.4% lower), the NVIDIA Quadro 4000 (4979, 0.8% lower), and the AMD Radeon R7 M340 (5063, 0.9% higher). The RTX 4070 GDDR6's rivals are the Intel Iris Pro Graphics 5200 (4360, 0.6% higher), the AMD FirePro W2100 (4295, 0.9% lower), the NVIDIA GeForce 930M (4388, 1.2% higher), and the NVIDIA GeForce GTX 460M (4282, 1.2% lower). The rival clusters are separated by over 600 points in average score, indicating that the two cards belong to different performance strata within the database.

The largest recorded win for the R5 M430 is its Geekbench Vulkan score of 4884, which is 12.7% higher than its own OpenCL score. The RTX 4070 GDDR6 has only one recorded benchmark, so no internal comparison exists. Across the database, the R5 M430's average score of 5018 is 15.7% higher than the RTX 4070 GDDR6's average of 4335, but this is an artifact of different test suites, not a meaningful performance advantage in real workloads.

Where Each One Wins

The R5 M430 wins in scenarios where the GPU must be integrated into a portable device with no discrete power delivery. Its IGP form factor, 64-bit DDR3 memory, and PCIe 3.0 x8 interface suit basic display output, legacy application acceleration, and low-power mobile platforms. The Geekbench OpenCL score of 5152 and Vulkan score of 4884 indicate that the R5 M430 can handle compute tasks that are not memory-bandwidth-bound, such as simple image processing or older API workloads. Its end-of-life status and GCN 1.0 architecture mean it has no ray tracing, no tensor cores, and no modern API features beyond Vulkan 1.2.170.

The RTX 4070 GDDR6 wins in nearly every measurable performance category. Its 29.15 TFLOPS FP32, 480.0 GB/s memory bandwidth, 46 ray tracing cores, and 184 tensor cores make it suitable for modern gaming, real-time ray tracing, AI inference, and content creation. The 12 GB GDDR6 frame buffer on a 192-bit bus supports high-resolution textures and large datasets. The dual-slot design with a 200 W TDP and 550 W suggested PSU indicates a dedicated power budget, unlike the R5 M430's integrated approach.

The RTX 4070 GDDR6 also wins on interface and display versatility. PCIe 4.0 x16 provides double the lane bandwidth of the R5 M430's PCIe 3.0 x8. The 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs support modern monitors and multi-display setups, while the R5 M430's outputs are dependent on the portable device's design.

The R5 M430's only practical advantage is its integration: no separate power connector, no slot width, no dimensions to accommodate. For a system where discrete graphics is impossible or unnecessary, the R5 M430 exists as a baseline. But the data shows no workload where the R5 M430 outperforms the RTX 4070 GDDR6 in raw throughput, memory bandwidth, or feature support. The RTX 4070 GDDR6 is the clear choice for any performance-oriented task, while the R5 M430 is limited to legacy or ultra-low-power contexts.
