Architecture Differences

The two cards represent fundamentally different design generations and foundry choices. The AMD Radeon RX 7400 OEM is built on RDNA 3.0 architecture using the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is manufactured on TSMC's 6 nm process. The NVIDIA RTX A1000 uses the Ampere architecture with the GA107 chip and belongs to the Workstation Ampere (Ax000) generation, manufactured on Samsung's 8 nm process.

The process node difference is substantial. AMD's 6 nm node allows for a transistor density of 65.2M per mm², while NVIDIA's 8 nm node achieves 43.5M per mm². Despite the density advantage, the AMD chip carries 13,300 million transistors on a 204 mm² die, whereas the NVIDIA chip carries 8,700 million transistors on a 200 mm² die. The die sizes are nearly identical, but AMD fits roughly 53% more transistors into a similar area.

Compute resource allocation differs significantly. The AMD card uses 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. The NVIDIA card has more shading units at 2304 but fewer TMUs at 72 and fewer ROPs at 32. For ray tracing, AMD includes 28 RT cores while NVIDIA includes 18 RT cores. NVIDIA adds 72 tensor cores, a feature the AMD card lacks entirely.

Clock behavior also diverges. The AMD Radeon RX 7400 OEM lists a base clock of 330 MHz and a boost clock of 1100 MHz. The NVIDIA RTX A1000 runs higher clocks, with a base of 727 MHz and a boost of 1462 MHz. Memory clocks differ as well: the AMD card runs at 1350 MHz with 10.8 Gbps effective, while the NVIDIA card runs at 1500 MHz with 12 Gbps effective.

Pixel and texture throughput reflect the different resource mixes. The AMD card achieves 70.40 GPixel/s and 123.2 GTexel/s. The NVIDIA card achieves 46.78 GPixel/s and 105.3 GTexel/s. AMD leads in both rasterization throughput metrics despite its lower clock speeds. FP16 throughput matches FP32 on both cards at a 1:1 ratio.

Physical and connectivity details differ. Both are single-slot cards, with the AMD measuring 167 mm in length and the NVIDIA at 163 mm. The AMD card uses a 6-pin power connector, while the NVIDIA card requires none. Display outputs diverge: the AMD card offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card offers 4x mini-DisplayPort 1.4a. Both use PCIe 4.0 x8 interfaces.

The Verdict

The recorded data supports a clear split by workload type. For raw rasterization throughput, the AMD Radeon RX 7400 OEM leads with higher pixel rate, texture rate, and FP32 compute. The data shows the AMD card delivers 70.40 GPixel/s versus 46.78 GPixel/s for NVIDIA, a 50.5% advantage in pixel fill, and 123.2 GTexel/s versus 105.3 GTexel/s, a 17.0% advantage in texture fill.

For memory-bound tasks, the NVIDIA RTX A1000 holds the advantage. Its 192.0 GB/s bandwidth exceeds the AMD card's 172.8 GB/s by 11.1%. The NVIDIA card also has a higher average benchmark score of 34207, placing it at the 79th percentile of all GPUs, while the AMD card has no recorded benchmarks and sits at the 50th percentile. The database shows the RTX A1000's nearest rivals include the NVIDIA RTX A2000 12 GB at 34154 (0.2% higher), the AMD Radeon RX 560 XT at 34133 (0.2% higher), and the NVIDIA TITAN V at 34355 (0.4% lower). These sub-1% deltas indicate the RTX A1000 performs in a tightly clustered band.

The AMD card's advantage in shading units, TMUs, ROPs, and RT cores suggests it is positioned for higher raw throughput in games and raster workloads. The NVIDIA card's tensor cores and higher memory bandwidth suggest it is positioned for workstation tasks that leverage those features. The RTX A1000's lack of a power connector and lower 50 W TDP also make it simpler to integrate into systems without auxiliary power.

Users whose workloads depend on pixel fill, texture throughput, or FP32 compute should favor the AMD Radeon RX 7400 OEM. Users whose workloads depend on tensor operations, memory bandwidth, or the validated benchmark results in the database should favor the NVIDIA RTX A1000.

Head-to-Head Benchmarks

No direct head-to-head benchmark results are recorded in the database for the AMD Radeon RX 7400 OEM versus the NVIDIA RTX A1000. The AMD card has an empty benchmark array and a wins count of zero. The NVIDIA card has three recorded benchmark results and a wins count of zero in the head-to-head comparison. The absence of shared test data means the comparison relies on specification-derived performance metrics.

The specification data provides indirect comparisons. In FP32 compute, the AMD card delivers 7.885 TFLOPS, which is 17.0% higher than the NVIDIA card's 6.737 TFLOPS. In pixel throughput, the AMD card's 70.40 GPixel/s exceeds the NVIDIA card's 46.78 GPixel/s by 50.5%. In texture throughput, the AMD card's 123.2 GTexel/s exceeds the NVIDIA card's 105.3 GTexel/s by 17.0%. The AMD card also has more TMUs (112 versus 72), more ROPs (64 versus 32), and more RT cores (28 versus 18).

The NVIDIA card counters in memory bandwidth, delivering 192.0 GB/s versus 172.8 GB/s, an 11.1% advantage. It also has more shading units at 2304 versus 1792, a 28.6% advantage, and it is the only card with tensor cores, offering 72 of them. The NVIDIA card's higher boost clock of 1462 MHz versus 1100 MHz helps close the throughput gap, but the AMD card's wider resource allocation maintains its lead in the aggregate throughput metrics.

The RTX A1000's benchmark record shows strong absolute performance. Its Geekbench OpenCL score is 52078 and its Geekbench Vulkan score is 49574. Its 3DMark Steel Nomad DX12 score is 969. These scores place it at the 79th percentile of all GPUs, with an average benchmark score of 34207.

The nearest rival data reinforces the RTX A1000's positioning. The NVIDIA RTX A2000 12 GB scores 34154, just 0.2% lower. The AMD Radeon RX 560 XT scores 34133, also 0.2% lower. The NVIDIA TITAN V scores 34355, which is 0.4% higher. The AMD Radeon RX 480 scores 33997, 0.6% lower. These narrow margins show the RTX A1000 operates within a competitive performance band defined by these four GPUs.

Where Each One Wins

The AMD Radeon RX 7400 OEM wins in scenarios that depend on rasterization throughput. Its 70.40 GPixel/s pixel rate is the highest among the two cards, and its 123.2 GTexel/s texture rate outpaces the NVIDIA card. The 7.885 TFLOPS FP32 throughput gives it an edge in compute workloads that scale with raw shading power. The larger count of TMUs (112), ROPs (64), and RT cores (28) supports workloads that stress these specific units. The AMD card also has a higher transistor density on a smaller process node, which may benefit efficiency in transistor-bound tasks.

The NVIDIA RTX A1000 wins in scenarios that depend on memory bandwidth and specialized compute. Its 192.0 GB/s bandwidth exceeds the AMD card's bandwidth, which benefits data-heavy workloads. The 2304 shading units provide more parallel shading capacity. The 72 tensor cores enable tensor-based operations that the AMD card cannot perform. The NVIDIA card's higher boost clock of 1462 MHz also gives it a clock-speed advantage in workloads sensitive to frequency.

The database's recorded benchmark results only cover the NVIDIA card, so validated performance data exists for the RTX A1000 but not for the AMD Radeon RX 7400 OEM. The RTX A1000's 79th percentile ranking with an average score of 34207 and its tight clustering with the RTX A2000 12 GB, RX 560 XT, TITAN V, and RX 480 provide a reference point for expected performance. The AMD card's 50th percentile ranking with no benchmark scores means its real-world standing is not established by the recorded data.

Workloads that prioritize pixel fill, texture throughput, and FP32 compute align with the AMD card. Workloads that prioritize memory bandwidth, tensor operations, and validated benchmark performance align with the NVIDIA card. The 50 W TDP and connector-free design of the NVIDIA card also make it the simpler installation option for systems without auxiliary power headers.
