Q: What benchmark data exists for these two cards?

A: The database contains no benchmark scores for the AMD Radeon RX 7400 OEM, giving it a percentile rank of 50 among all GPUs. The NVIDIA RTX 5000 Ada Generation has scores of 175286 in Geekbench OpenCL and 194041 in Geekbench Vulkan, placing it at the 98th percentile.

Where Each One Wins

The NVIDIA RTX 5000 Ada Generation dominates every measurable performance category in the recorded data. Its average benchmark score of 184664 places it at the 98th percentile among all GPUs, while the AMD Radeon RX 7400 OEM has no recorded benchmark scores and sits at the 50th percentile. The NVIDIA card wins both available benchmarks outright: Geekbench OpenCL at 175286 and Geekbench Vulkan at 194041, with zero recorded scores for the AMD side.

The AMD card wins in power efficiency and physical footprint. Its 55 W TDP is less than one quarter of NVIDIA's 250 W TDP. The AMD card is a single-slot, 167 mm design versus NVIDIA's dual-slot, 267 mm design. These factors make the AMD card suitable for compact, low-power systems, though the data provides no performance evidence to support its use in compute-heavy workloads.

The NVIDIA card wins in memory capacity, bandwidth, and raw compute throughput. Its 32 GB memory capacity is four times larger than AMD's 8 GB. Its 576.0 GB/s bandwidth is more than triple AMD's 172.8 GB/s. The NVIDIA card also delivers 65.28 TFLOPS FP32 performance versus AMD's 7.885 TFLOPS, an eightfold advantage.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The AMD Radeon RX 7400 OEM uses RDNA 3.0 architecture on a 6 nm TSMC process with 13,300 million transistors on a 204 mm² die. The NVIDIA RTX 5000 Ada Generation uses Ada Lovelace architecture on a 5 nm TSMC process with 76,300 million transistors on a 609 mm² die. NVIDIA's chip has nearly six times the transistor count and roughly three times the die area.

The compute pipelines diverge significantly. The AMD card has 1792 shading units, 112 texture mapping units, and 64 ROPs. The NVIDIA card has 12800 shading units, 400 texture mapping units, and 176 ROPs, representing increases of over seven times, three and a half times, and nearly three times respectively.

Ray tracing and tensor capabilities differ sharply. The AMD card has 28 ray tracing cores and no tensor cores. The NVIDIA card has 100 ray tracing cores and 400 tensor cores. The presence of tensor cores gives NVIDIA a hardware advantage for AI and deep learning workloads that the AMD card cannot match.

Memory architecture reflects the different target markets. Both use GDDR6 memory, but AMD's 128 bit bus versus NVIDIA's 256 bit bus creates a bandwidth gap that affects high-resolution texture streaming and large dataset processing. The AMD card's 8 GB capacity suggests a mainstream consumer orientation, while NVIDIA's 32 GB capacity indicates professional workstation usage.

Specification Differences

The clock speeds show a notable divergence. The AMD card has a base clock of 330 MHz and a boost clock of 1100 MHz. The NVIDIA card has a base clock of 1155 MHz and a boost clock of 2550 MHz, with the boost clock more than double AMD's. Memory clocks also differ: AMD runs at 1350 MHz with 10.8 Gbps effective, while NVIDIA runs at 2250 MHz with 18 Gbps effective.

Pixel and texture rates favor NVIDIA decisively. The AMD card delivers 70.40 GPixel/s and 123.2 GTexel/s. The NVIDIA card delivers 448.8 GPixel/s and 1,020.0 GTexel/s, representing roughly sixfold and eightfold advantages respectively.

The interface and display outputs differ. AMD uses PCIe 4.0 x8 with 1x HDMI 2.1a and 3x DisplayPort 2.1. NVIDIA uses PCIe 4.0 x16 with 4x DisplayPort 1.4a. The wider PCIe interface on NVIDIA doubles the available bus lanes.

Physical specifications show distinct design targets. The AMD card is single-slot, 167 mm long, with a 55 W TDP and one 6-pin power connector. The NVIDIA card is dual-slot, 267 mm long and 112 mm high, with a 250 W TDP and one 16-pin power connector. The suggested power supply scales accordingly: 250 W for AMD versus 600 W for NVIDIA.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status differs, with NVIDIA listed as Active while AMD has no recorded production status. Release dates also differ: AMD released on 2025-08-07 while NVIDIA released on 2023-08-08.

Head-to-Head Benchmarks

The recorded data shows a complete absence of head-to-head benchmark results between these two GPUs. The head-to-head benchmark array is empty, and the AMD card has no individual benchmark scores at all. The only performance measurements in the database belong to the NVIDIA RTX 5000 Ada Generation.

The NVIDIA card's Geekbench OpenCL score of 175286 and Geekbench Vulkan score of 194041 establish a performance baseline that cannot be compared directly to AMD, since the AMD card has no scores. The average benchmark score of 184664 for NVIDIA places it among high-end workstation parts. Its nearest rivals include the NVIDIA A100 SXM4 80 GB at 183725, a 0.5% delta, and the NVIDIA A100 SXM4 40 GB at 187147, a -1.3% delta. The NVIDIA RTX PRO 5000 Blackwell scores 182109, a 1.4% delta, and the NVIDIA GeForce RTX 4090 D scores 178050, a 3.7% delta.

These deltas indicate that the RTX 5000 Ada Generation sits in a tight performance band with other top-tier NVIDIA workstation and enthusiast cards. The AMD Radeon RX 7400 OEM has no corresponding data, so any direct comparison of benchmark performance is impossible from the recorded measurements. The percentile ranks tell the story: NVIDIA at the 98th percentile versus AMD at the 50th percentile, a gap that reflects both the absence of AMD scores and the strength of NVIDIA's recorded results.

The Verdict

The data supports a clear conclusion: the NVIDIA RTX 5000 Ada Generation is the overwhelmingly more capable GPU for compute-intensive tasks. Its 65.28 TFLOPS FP32 performance, 32 GB memory capacity, and 576.0 GB/s bandwidth position it as a professional-grade workstation card. Its 98th percentile rank and average benchmark score of 184664 confirm its standing among the fastest accelerators in the database. The 400 tensor cores provide dedicated hardware for AI workloads, and the 100 ray tracing cores deliver substantial real-time rendering capability.

The AMD Radeon RX 7400 OEM serves a different purpose entirely. Its 55 W TDP, single-slot design, and 167 mm length make it appropriate for low-power, space-constrained systems. Its 8 GB memory and 172.8 GB/s bandwidth suit lighter workloads, and its PCIe 4.0 x8 interface reflects a more modest data throughput requirement. The 28 ray tracing cores provide some acceleration for ray-traced content, but the absence of tensor cores limits its utility for machine learning applications.

The specification disparities are stark. The NVIDIA card offers 7.1 times the shading units, 3.6 times the texture mapping units, 2.75 times the ROPs, 3.6 times the ray tracing cores, and 8.3 times the FP32 throughput. Its memory bandwidth advantage of 576.0 GB/s versus 172.8 GB/s represents a 3.3 times gap. Its 250 W TDP and 600 W suggested PSU reflect the power required to feed those resources.

For users processing large datasets, training neural networks, or rendering complex scenes, the NVIDIA RTX 5000 Ada Generation is the only viable choice based on the recorded data. For basic graphics output, low-power operation, or compact builds, the AMD Radeon RX 7400 OEM offers a functional alternative, though its performance is unquantified in the database. The NVIDIA card's active production status and established benchmark results provide confidence in its capabilities, while the AMD card's lack of recorded scores leaves its real-world performance undefined.
