AMD Radeon 8065S vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Radeon 8065S versus the NVIDIA N1 20SM. Both entries show empty benchmark arrays, zero wins in the wins tally, and an average benchmark score of 0. The percentile ranking for both parts sits at 50, placing them at the midpoint of all GPUs in the database, but this is a neutral position rather than a competitive measurement.

Without direct benchmark comparisons, the available performance indicators come from the recorded specification data. The AMD Radeon 8065S delivers 15.36 TFLOPS FP32 performance, which is 27.9% higher than the NVIDIA N1 20SM's 12.01 TFLOPS FP32 figure. The texture rate follows a similar pattern: the AMD part reaches 480.0 GTexel/s against the NVIDIA part's 375.4 GTexel/s, a 27.9% advantage in texture throughput. The pixel rate gap is larger, with the Radeon 8065S posting 192.0 GPixel/s versus 56.30 GPixel/s for the N1 20SM, a 241.0% difference that reflects the NVIDIA part's much lower ROP count.

Clock speeds show a substantial divergence. The AMD Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The NVIDIA N1 20SM operates at 741 MHz base and 2346 MHz boost. The AMD boost clock is 27.9% higher than the NVIDIA boost clock, and the base clock advantage is 74.8%. These clock differences contribute directly to the FP32 and texture rate deltas, since both parts share the same 2560 shading units and 160 texture mapping units.

Memory configuration separates the two clearly. The NVIDIA N1 20SM uses 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The AMD Radeon 8065S uses system shared memory, with bandwidth listed as system dependent, making direct memory throughput comparison impossible from the recorded data. The NVIDIA part's memory clock is listed as 1067 MHz with 8.5 Gbps effective transfer rate.

Where Each One Wins

The AMD Radeon 8065S wins on raw compute throughput. Its 15.36 TFLOPS FP32 output exceeds the NVIDIA N1 20SM's 12.01 TFLOPS by 27.9%. The same percentage advantage appears in texture fill rate, where 480.0 GTexel/s beats 375.4 GTexel/s. The pixel fill rate advantage is far more pronounced: 192.0 GPixel/s against 56.30 GPixel/s, a 3.4x margin. These figures indicate the AMD part processes rasterization work substantially faster, due to its 64 ROPs versus 24 ROPs on the NVIDIA part.

The AMD part also clocks higher across the board. The 3000 MHz boost clock and 1295 MHz base clock both exceed the NVIDIA part's 2346 MHz boost and 741 MHz base. Higher clocks with identical shader and TMU counts translate directly into the compute and texture advantages noted above.

The NVIDIA N1 20SM wins on memory capacity and bandwidth. Its 128 GB LPDDR5X pool with 273.2 GB/s bandwidth is a fixed, dedicated resource. The AMD Radeon 8065S relies on system shared memory with bandwidth marked as system dependent, meaning its memory performance varies with the host platform. The NVIDIA part also integrates 80 tensor cores, while the AMD part lists no tensor core count. The NVIDIA part includes 20 RT cores versus 40 on the AMD part, though the AMD part's higher clock speed likely offsets some of that raw core count difference in ray tracing throughput.

The NVIDIA N1 20SM has a larger die at 382 mm² versus 308 mm² for the AMD Radeon 8065S, despite using a 5 nm process compared to AMD's 4 nm node. Both come from TSMC. The AMD part achieves higher performance per die area based on the compute figures, though the NVIDIA part's additional tensor cores and larger memory interface occupy die space.

The Verdict

The recorded data indicates the AMD Radeon 8065S is the stronger choice for raw graphics compute. Its 15.36 TFLOPS FP32, 480.0 GTexel/s texture rate, and 192.0 GPixel/s pixel rate all exceed the NVIDIA N1 20SM's corresponding figures by margins ranging from 27.9% to 241.0%. The AMD part's higher clocks, 3000 MHz boost versus 2346 MHz, and double the ROP count, 64 versus 24, drive these advantages. For applications that stress pixel throughput, such as high-resolution rasterization, the AMD part holds a decisive edge.

The NVIDIA N1 20SM is the choice for workloads that need substantial dedicated memory. Its 128 GB LPDDR5X pool with 273.2 GB/s bandwidth is a fixed resource, whereas the AMD part's system shared memory configuration leaves bandwidth dependent on the host system. The NVIDIA part's 80 tensor cores also give it a dedicated pathway for AI and machine learning workloads, something the AMD part lacks entirely in the recorded specifications.

The AMD Radeon 8065S uses RDNA 3.5 architecture on a 4 nm TSMC process with a 308 mm² die. The NVIDIA N1 20SM uses Blackwell 2.0 architecture on a 5 nm TSMC process with a 382 mm² die. The AMD part lists a 55 W TDP, while the NVIDIA part's TDP is unknown. Both are integrated graphics processors with no power connectors and PCIe 5.0 x16 interfaces.

Users who prioritize raw rendering performance should select the AMD Radeon 8065S based on the compute and fill rate data. Users who need large dedicated memory or tensor core acceleration should select the NVIDIA N1 20SM. The AMD part's system shared memory could be a limitation in memory-heavy scenarios, but the recorded data does not quantify that impact.
