AMD Radeon 8065S vs NVIDIA N1X 48SM Comparison

Where Each One Wins

The AMD Radeon 8065S and NVIDIA N1X 48SM occupy the same integrated graphics slot, but their recorded data points to entirely different strengths. The AMD part, built on RDNA 3.5, is configured around a moderate shader count with a very high boost clock. Its pixel throughput of 192.0 GPixel/s is substantially higher than the NVIDIA part's 112.6 GPixel/s, which suggests the AMD solution carries a decisive advantage in fill-rate-bound workloads such as traditional rasterization at high resolutions. Texture rate also favors AMD at 480.0 GTexel/s, though the NVIDIA part counters with 900.9 GTexel/s, a notable inversion that indicates NVIDIA's architecture leans on texture-heavy shader work.

The NVIDIA N1X 48SM wins where compute throughput and memory bandwidth dominate. Its FP32 output of 28.83 TFLOPS nearly doubles the AMD part's 15.36 TFLOPS, and its FP16 rate matches at 28.83 TFLOPS, again versus 15.36 TFLOPS. For any workload that scales with raw shader math, machine learning inference, or FP16 tensor operations, the NVIDIA part is the clear leader. The NVIDIA part also ships with 128 GB of LPDDR5X memory on a 256-bit bus, yielding 273.2 GB/s of bandwidth. The AMD part uses system-shared memory with bandwidth listed as system dependent, so in a fixed configuration the NVIDIA part offers a predictable, high-bandwidth memory pool while AMD's performance scales with the host system's memory design.

The recorded percentile data places both parts at the 50th percentile against all GPUs, and neither has an average benchmark score or nearest rivals recorded. That means the database currently holds no direct measured performance deltas for either part. The wins listed here come from the architectural specifications: AMD wins in pixel rate and offers a 3000 MHz boost clock versus NVIDIA's 2346 MHz, while NVIDIA wins in shading units, texture rate, FP32, FP16, memory capacity, and memory bandwidth.

Architecture Differences

The two integrated GPUs come from different foundries and process nodes. AMD uses TSMC's 4 nm process for the Gorgon Halo chip, while NVIDIA uses TSMC's 5 nm process for the GB20B die. The AMD die measures 308 mm², the NVIDIA die measures 382 mm². Both are listed as active production parts with no transistor counts recorded.

The AMD Radeon 8065S belongs to the Navi Mobile (RX 8000M) generation and uses RDNA 3.5. It carries 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. The NVIDIA N1X 48SM belongs to the Blackwell IGP (N1x) generation and uses Blackwell 2.0. It carries 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The AMD part has no tensor core count listed, while NVIDIA's tensor core count is substantial for an integrated part.

Clock behavior differs sharply. The AMD part has a base clock of 1295 MHz and a boost of 3000 MHz. The NVIDIA part has a base of 741 MHz and a boost of 2346 MHz. AMD's boost advantage of 654 MHz helps close some of the raw shader-count gap in single-threaded or lightly threaded workloads, though the NVIDIA part's 2.4x shader count still dominates aggregate FP32 throughput.

Memory architecture is a fundamental split. The AMD Radeon 8065S uses system-shared memory with a system-shared bus width and system-dependent bandwidth. The NVIDIA N1X 48SM uses 128 GB of LPDDR5X on a 256-bit bus with a fixed 273.2 GB/s bandwidth and a memory clock of 1067 MHz (8.5 Gbps effective). The AMD part's memory clock is listed as system shared, meaning no dedicated VRAM clock is specified. The NVIDIA part also has a defined display output of one HDMI port, while AMD's display outputs are portable device dependent.

API support also differs. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan, which is unusual for a GPU and suggests the database has not recorded API compatibility for this part yet. Both use a PCIe 5.0 x16 bus interface, both are IGP slot width, and both use no power connectors. The NVIDIA TDP is unknown while AMD lists 55 W.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries for these two parts, and both carry an average benchmark score of zero. Direct measured deltas cannot be cited. However, the specification-level comparisons provide concrete numerical gaps that indicate how each part would perform in different workload classes.

The largest NVIDIA advantage is in FP32 compute. At 28.83 TFLOPS versus 15.36 TFLOPS, the NVIDIA part delivers 13.47 TFLOPS more, which is 87.7% higher than AMD's figure. FP16 follows the same pattern: 28.83 TFLOPS versus 15.36 TFLOPS, again an 87.7% advantage for NVIDIA. Texture rate favors NVIDIA at 900.9 GTexel/s versus 480.0 GTexel/s, a difference of 420.9 GTexel/s, or 87.7% higher. Shading units favor NVIDIA at 6144 versus 2560, a 3584-unit gap. TMUs favor NVIDIA at 384 versus 160. Memory bandwidth favors NVIDIA at 273.2 GB/s versus system dependent.

The AMD advantages are smaller in number but clear in direction. Pixel rate sits at 192.0 GPixel/s versus NVIDIA's 112.6 GPixel/s, a 79.4 GPixel/s gap, or 70.5% higher for AMD. Boost clock sits at 3000 MHz versus 2346 MHz, a 654 MHz gap, or 27.9% higher. The AMD part also has 64 ROPs versus NVIDIA's 48, a 16 ROP advantage. AMD's base clock of 1295 MHz is 554 MHz higher than NVIDIA's 741 MHz. The AMD die is smaller at 308 mm² versus 382 mm², a 74 mm² difference, though die size alone does not determine performance.

The practical interpretation from these numbers: NVIDIA's part is built for compute-heavy and texture-heavy workloads, with more than double the shading units and FP32 throughput. AMD's part is built for fill-rate-bound rendering, with a higher pixel rate and more ROPs despite fewer shading units. The 87.7% advantage NVIDIA holds in FP32, FP16, and texture rate is consistent across all three metrics, indicating a deliberate architectural balance rather than an anomaly. AMD's 70.5% pixel-rate advantage is similarly consistent with its ROP and clock configuration.
