AMD Radeon 8065S vs NVIDIA L4 Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two accelerators, primarily because the AMD Radeon 8065S has no benchmark entries in the database while the NVIDIA L4 has two recorded scores. The L4 delivers a Geekbench OpenCL score of 140,838 and a Geekbench Vulkan score of 121,306, producing an average benchmark score of 131,072. The Radeon 8065S, by contrast, shows an average benchmark score of 0 with no individual test results, meaning direct numerical comparison is impossible from the available measurements.

The NVIDIA L4 sits in the 95th percentile among all GPUs in the database, a position that places it well above the Radeon 8065S, which sits at the 50th percentile with a zero score. The L4's nearest rivals in the database include the NVIDIA GeForce RTX 3090 Ti with an average score of 131,938, which is 0.7% higher than the L4, and the NVIDIA RTX 4000 Ada Generation at 135,218, which is 3.1% higher. The AMD Radeon PRO W6800 also appears at 135,396, again 3.2% ahead of the L4. These deltas show the L4 is competitive with high-end desktop and professional cards from the previous generation, trailing them by only a few percentage points.

Since the Radeon 8065S has no benchmark entries, the head-to-head comparison contains zero wins for either side in the formal wins tally. This does not mean the AMD part is uncompetitive, it means the database lacks recorded measurements for it. The L4's FP32 compute of 30.29 TFLOPS versus the Radeon's 15.36 TFLOPS indicates a 97% advantage for NVIDIA in raw single-precision throughput, based purely on the specification data. The texture rate also favors the L4 at 489.6 GTexel/s versus 480.0 GTexel/s, a narrow 2% margin, while the pixel rate favors the AMD part at 192.0 GPixel/s versus 163.2 GPixel/s, an 18% lead.

Where Each One Wins

The NVIDIA L4 wins decisively in compute density and memory configuration. It packs 7,424 shading units, 240 texture mapping units, 80 render output units, 60 ray tracing cores, and 240 tensor cores into a 72 W package. The Radeon 8065S offers 2,560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores with no tensor core count listed. The L4 also has a fixed 24 GB of GDDR6 memory on a 192-bit bus with 300.1 GB/s of bandwidth, whereas the Radeon uses system shared memory with bandwidth described as system dependent.

The Radeon 8065S wins on clock speeds. Its base clock of 1295 MHz and boost clock of 3000 MHz both exceed the L4's 795 MHz base and 2040 MHz boost. The AMD part also has a higher pixel rate, 192.0 GPixel/s versus 163.2 GPixel/s, which suggests stronger fill-rate performance in rasterization-bound workloads. The Radeon uses a newer PCIe 5.0 x16 interface while the L4 uses PCIe 4.0 x16, giving the AMD part twice the interconnect bandwidth for data transfer, though the practical impact depends on system memory speed and workload.

The L4's tensor cores give it a clear advantage for AI and machine learning inference tasks, a category where the Radeon has no listed equivalent hardware. The L4 also has a higher transistor count at 35,800 million versus unknown for the Radeon, and a higher transistor density of 121.8M per mm². Both parts support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API-level features are identical.

The Verdict

Based on the recorded data, the NVIDIA L4 is the only part with verified benchmark performance. Its 131,072 average score places it at the 95th percentile, and its nearest rivals show it is within 0.7% of the GeForce RTX 3090 Ti and within 3.2% of the Radeon PRO W6800. The Radeon 8065S has no measured scores, so any claim of performance superiority for AMD cannot be supported by the database.

For compute-heavy workloads such as FP32 math, the L4 delivers 30.29 TFLOPS versus 15.36 TFLOPS, a 97% advantage. For memory-intensive tasks, the L4's dedicated 24 GB GDDR6 with 300.1 GB/s bandwidth is a fixed resource, while the Radeon depends entirely on system RAM, which introduces variable performance. The L4 also offers tensor cores for AI acceleration, a feature absent from the Radeon's specification sheet.

The Radeon 8065S has advantages in clock speed, pixel rate, and power consumption at 55 W versus 72 W for the L4. It also uses a more modern PCIe 5.0 interface. However, without benchmark scores, these advantages remain theoretical. The database shows the L4 as an active, tested product with a clear performance profile, while the Radeon 8065S is listed as active but untested. Anyone selecting between these two should prioritize the L4 if verified performance matters, and should treat the Radeon's specifications as unvalidated potential.
