AMD Radeon RX 7400 OEM vs NVIDIA GB10 Comparison

Where Each One Wins

The recorded data separates these two GPUs into entirely different performance classes. The NVIDIA GB10 holds the dominant position in every measurable benchmark category, while the AMD Radeon RX 7400 OEM has no benchmark entries in the database. This means the GB10 takes all wins by default, but the nature of those wins matters more than the simple count.

The GB10 posts an average benchmark score of 117,393 across two recorded tests: Geekbench OpenCL at 120,137 and Geekbench Vulkan at 114,648. The RX 7400 OEM shows zero benchmark scores, placing it at the 50th percentile among all GPUs in the database. The GB10, by contrast, sits at the 95th percentile, a position that puts it ahead of roughly 95% of all recorded graphics hardware.

The RX 7400 OEM is not without its own strengths, but those strengths are architectural rather than measured. It targets a low-power, single-slot desktop OEM form factor with a 55 W TDP, while the GB10 is an integrated graphics processor (IGP) with a 140 W TDP. The use-case split is clear: the RX 7400 OEM fits compact office or media systems where power draw and slot space are constrained, while the GB10 serves compute-oriented server workloads where raw throughput dominates.

In practical terms, the GB10 wins every performance comparison the database can support. The RX 7400 OEM wins on power efficiency per watt on paper, but no benchmark data confirms real-world efficiency. The GB10 also carries a launch MSRP of 3,999 USD, a figure that positions it as a high-end compute part rather than a consumer graphics card.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7400 OEM and the GB10. The available comparison comes from the GB10's standalone benchmark results and its nearest rival data.

The GB10's Geekbench OpenCL score of 120,137 represents its strongest recorded result. Its Geekbench Vulkan score of 114,648 trails by about 4.6% internally. Against its nearest rivals, the GB10 leads the NVIDIA RTX 4000 SFF Ada Generation by 0.3% (117,088 average score), the NVIDIA Tesla V100 SXM2 16 GB by 2.6% (114,395), and the NVIDIA RTX A5500 Mobile by 3% (113,944). The AMD Radeon PRO W7700 beats the GB10 by 1.3% with an average score of 118,976.

The RX 7400 OEM cannot be placed in this comparison because it has no recorded scores. Its theoretical compute figures, however, show a large gap. The GB10 delivers 29.71 TFLOPS FP32 and 29.71 TFLOPS FP16, while the RX 7400 OEM delivers 7.885 TFLOPS FP32 and 7.885 TFLOPS FP16. The GB10's FP32 throughput is approximately 3.8 times higher. The GB10 also leads in pixel rate at 116.1 GPixel/s versus 70.40 GPixel/s and in texture rate at 928.5 GTexel/s versus 123.2 GTexel/s, the latter being a 7.5 times advantage.

The RX 7400 OEM does lead in one specification category: render output units. It has 64 ROPs versus the GB10's 48 ROPs. This suggests the AMD part may handle certain rasterization-bound workloads more efficiently on a per-clock basis, though the GB10's much higher clock speeds and shading unit count overwhelm this advantage in aggregate throughput.

Clock speeds further separate the two. The GB10 runs at a 1665 MHz base and 2418 MHz boost, while the RX 7400 OEM runs at 330 MHz base and 1100 MHz boost. The GB10's boost clock is more than double the AMD part's base clock, and its memory clock of 1067 MHz (8.5 Gbps effective) on a 256-bit bus produces 273.2 GB/s of bandwidth versus the RX 7400 OEM's 1350 MHz (10.8 Gbps effective) on a 128-bit bus producing 172.8 GB/s.

Specification Differences

The two GPUs differ across nearly every measurable specification.

Memory is the most dramatic gap. The GB10 carries 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The RX 7400 OEM carries 8 GB of GDDR6 on a 128-bit bus with 172.8 GB/s bandwidth. That is a 16 times difference in capacity and a 1.6 times difference in bandwidth.

Compute resources favor the GB10 heavily. It has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 384 tensor cores. The RX 7400 OEM has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, with no tensor cores listed. The GB10 has 3.4 times more shading units, 3.4 times more TMUs, and 1.7 times more RT cores. The RX 7400 OEM counters with 1.3 times more ROPs.

Clock speeds favor the GB10. Its base clock is 1665 MHz and boost is 2418 MHz. The RX 7400 OEM runs at 330 MHz base and 1100 MHz boost. The GB10's memory runs at 1067 MHz (8.5 Gbps effective) versus the RX 7400 OEM's 1350 MHz (10.8 Gbps effective).

Power and physical design differ substantially. The RX 7400 OEM draws 55 W, uses a single 6-pin connector, and requires a suggested 250 W power supply. The GB10 draws 140 W, uses no power connectors, and requires a suggested 300 W power supply. The RX 7400 OEM is a single-slot card at 167 mm length, while the GB10 is an integrated graphics processor measuring 150 by 51 by 150 mm.

Bus interface and display outputs also differ. The RX 7400 OEM uses PCIe 4.0 x8 and provides 1x HDMI 2.1a plus 3x DisplayPort 2.1. The GB10 uses PCIe 5.0 x16 and provides only 1x HDMI. The RX 7400 OEM supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the GB10 lists N/A for all three.

Process node and die details show different design priorities. Both use TSMC fabrication, but the RX 7400 OEM uses a 6 nm process with a 204 mm² die containing 13,300 million transistors at a density of 65.2M per mm². The GB10 uses a 5 nm process with a 382 mm² die and unknown transistor count. The GB10's die is 1.9 times larger.

Architecture Differences

The RX 7400 OEM is built on RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and the Radeon RX 7000 series. Its predecessor is Navi II and its successor is Navi IV. The architecture uses a 6 nm TSMC process.

The GB10 is built on Blackwell 2.0 architecture with the GB20B chip and belongs to the Server Blackwell (Bxx) generation. Its predecessor is Server Hopper and its successor is Server Rubin. The architecture uses a 5 nm TSMC process. No codename is listed for the GB10.

The architectural divide is fundamental. RDNA 3.0 is a graphics-first architecture designed for rasterization and real-time rendering workloads. Blackwell 2.0 is a compute-first architecture designed for server and data center workloads. The API support confirms this: the RX 7400 OEM supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the GB10 lists N/A for all three graphics APIs. The GB10 instead emphasizes tensor cores, with 384 of them, a feature the RX 7400 OEM lacks entirely.

Ray tracing hardware also differs. The GB10 has 48 RT cores versus the RX 7400 OEM's 28 RT cores. Both support ray tracing, but the GB10 has 1.7 times the hardware dedicated to it. The GB10's 384 tensor cores provide dedicated AI and matrix math acceleration, which the RX 7400 OEM does not offer.

The process nodes reflect a generational shift. The RX 7400 OEM uses 6 nm TSMC, while the GB10 uses 5 nm TSMC. The GB10's die is 382 mm² versus 204 mm² for the RX 7400 OEM, and the GB10's transistor count is unknown while the RX 7400 OEM lists 13,300 million. The GB10's transistor density is not recorded, but its larger die and newer process suggest a significantly higher transistor budget.

Memory architecture differs as well. The RX 7400 OEM uses GDDR6, a dedicated graphics memory type, while the GB10 uses LPDDR5X, a low-power memory typically used in mobile and server contexts. The GB10's 256-bit bus is twice the width of the RX 7400 OEM's 128-bit bus.

Production status also separates the two. The GB10 is listed as Active with a release date of October 14, 2025. The RX 7400 OEM has no production status listed and a release date of August 7, 2025. The RX 7400 OEM is an OEM part, meaning it is intended for system integrators rather than retail sale.

The Verdict

The data supports a straightforward choice for most users. The NVIDIA GB10 is the far more capable processor, with a 95th percentile ranking, an average benchmark score of 117,393, and leading results in both Geekbench OpenCL (120,137) and Geekbench Vulkan (114,648). It delivers 29.71 TFLOPS FP32, 128 GB of memory, and 384 tensor cores. The RX 7400 OEM cannot match these figures in any benchmark category, as it has no recorded scores.

The RX 7400 OEM is a low-power graphics card for OEM systems. Its 55 W TDP, single-slot design, and 167 mm length make it suitable for compact builds. Its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 means it can run conventional graphics workloads and games. Its 8 GB of GDDR6 memory and 172.8 GB/s bandwidth are modest but appropriate for its class.

The GB10 is not a graphics card in the conventional sense. It lists N/A for DirectX, OpenGL, and Vulkan, and its 3,999 USD launch MSRP places it in server hardware territory. Its 140 W TDP, lack of power connectors, and 300 W suggested power supply indicate it draws power through its host system rather than dedicated PCIe cables. Its 128 GB of LPDDR5X memory and 273.2 GB/s bandwidth serve compute and AI workloads, not gaming.

Users building a desktop PC with standard graphics API requirements should choose the RX 7400 OEM. Users deploying server or compute systems that do not need conventional graphics APIs should choose the GB10. The benchmark data shows no scenario where the RX 7400 OEM outperforms the GB10, but the two serve such different purposes that direct competition does not exist in practice.
