AMD Radeon 8065S vs NVIDIA GeForce RTX 4050 Mobile Comparison

The Verdict

The AMD Radeon 8065S and NVIDIA GeForce RTX 4050 Mobile represent two fundamentally different approaches to mobile graphics, and the recorded data indicates distinct strengths that suit different usage profiles. The Radeon 8065S uses a newer process node, a larger die, and significantly higher clock speeds, delivering roughly 70% more raw FP32 throughput than its rival. The RTX 4050 Mobile, however, holds the only concrete benchmark results in the database, with an average benchmark score of 19049 and a percentile ranking of 63, placing it above the Radeon's percentile of 50.

For users prioritizing raw compute performance, the Radeon 8065S is the clear choice based on its recorded specifications. Its FP32 throughput of 15.36 TFLOPS dwarfs the RTX 4050 Mobile's 8.986 TFLOPS, and its texture rate of 480.0 GTexel/s is more than triple the NVIDIA part's 140.4 GTexel/s. The Radeon also doubles the pixel rate at 192.0 GPixel/s versus 84.24 GPixel/s. These figures indicate a substantial advantage in fill-rate-bound workloads and general compute tasks.

The RTX 4050 Mobile, by contrast, has actual measured performance data in the database, which the Radeon 8065S lacks entirely. Its benchmark scores across OpenCL, Vulkan, DirectX, and PassMark suites provide a verified baseline. The NVIDIA part also carries 80 tensor cores versus zero for the Radeon, making it the only option with dedicated AI acceleration hardware. For applications that leverage tensor cores, the RTX 4050 Mobile has a functional advantage that raw FP32 numbers cannot offset.

The verdict from the data: the Radeon 8065S is the superior choice for raw rasterization throughput and compute-heavy workloads where its FP32 and texture rates translate directly to performance. The RTX 4050 Mobile is the safer pick for users who need verified benchmark results, tensor-based AI acceleration, and a smaller, more efficient chip. Neither part is universally better; the choice depends entirely on whether the workload values raw throughput or measured results and AI features.

Architecture Differences

The two GPUs diverge sharply at the architectural level. The Radeon 8065S is built on RDNA 3.5, AMD's latest graphics architecture, using a 4 nm TSMC process. Its chip, codenamed Gorgon Halo, measures 308 mm², a substantial die that reflects its integrated design. The RTX 4050 Mobile uses Ada Lovelace, NVIDIA's architecture for the GeForce 40-series, fabricated on a 5 nm TSMC process. Its AD107 chip is considerably smaller at 159 mm², with 18,900 million transistors and a transistor density of 118.9M per mm². The Radeon's transistor count is listed as unknown in the database.

Clock behavior presents another major contrast. The Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, an aggressive boost curve that drives its high throughput. The RTX 4050 Mobile operates at a base of 1455 MHz and boosts to 1755 MHz, a much more conservative range. Despite the NVIDIA part starting from a higher base, the Radeon's boost clock is over 70% higher, which directly explains its TFLOPS advantage.

Memory architecture differs fundamentally. The Radeon 8065S uses system shared memory with system dependent bandwidth, meaning its performance scales with the host platform's RAM configuration. The RTX 4050 Mobile has dedicated 6 GB of GDDR6 memory on a 96-bit bus, delivering a fixed 192.0 GB/s bandwidth. This gives the NVIDIA part predictable memory performance, while the Radeon's memory behavior cannot be characterized without knowing the system memory specs.

Shader resources show both similarity and divergence. Both GPUs have 2560 shading units, but the Radeon 8065S has 160 texture mapping units and 64 render output units, versus 80 TMUs and 48 ROPs for the RTX 4050 Mobile. The Radeon also has 40 ray tracing cores, double the RTX 4050 Mobile's 20, but the NVIDIA part counters with 80 tensor cores, a feature the Radeon lacks entirely. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Power and interface differences round out the architectural picture. The Radeon 8065S has a TDP of 55 W, slightly above the RTX 4050 Mobile's 50 W. Both are integrated GPUs with no power connectors. The Radeon uses PCIe 5.0 x16, while the RTX 4050 Mobile uses PCIe 4.0 x8, giving the AMD part twice the PCIe lanes on a newer bus revision. The Radeon's release date is recorded as late 2025, while the RTX 4050 Mobile launched in early 2023, a generational gap of nearly three years.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, so the comparison must be drawn from their recorded specifications and the RTX 4050 Mobile's standalone benchmark scores.

The most decisive specification advantage belongs to the Radeon 8065S in texture throughput. Its texture rate of 480.0 GTexel/s is 241.9% higher than the RTX 4050 Mobile's 140.4 GTexel/s, a gap that will manifest in any texture-bound rendering scenario. The pixel rate tells a similar story: 192.0 GPixel/s versus 84.24 GPixel/s, a 128% advantage for the AMD part. These are the largest proportional gaps in the entire comparison, indicating that the Radeon's 160 TMUs and 64 ROPs provide a structural advantage that clock speed alone cannot overcome in the NVIDIA part.

FP32 compute follows the same pattern. The Radeon 8065S delivers 15.36 TFLOPS, which is 70.9% higher than the RTX 4050 Mobile's 8.986 TFLOPS. Both GPUs maintain a 1:1 ratio for FP16, so the same proportional gap applies to half-precision workloads. This makes the Radeon the stronger choice for compute-heavy applications such as scientific simulation, rendering, and any workload that scales with shader throughput.

The RTX 4050 Mobile's recorded benchmarks provide a reference point that the Radeon cannot match in the database. Its Geekbench scores are 74748 for OpenCL and 75235 for Vulkan. In PassMark tests, it scores 14423 in G3D, 5947 in GPU compute, 633 in G2D, 184 in DirectX 9, 130 in DirectX 11, 79 in DirectX 10, and 61 in DirectX 12. These results give the NVIDIA part an average benchmark score of 19049, placing it in the 63rd percentile of all GPUs. The Radeon 8065S has no recorded benchmark scores, an average score of 0, and sits at the 50th percentile.

The nearest rivals to the RTX 4050 Mobile offer context for its standing. The AMD Radeon RX 6600 scores 19036, a 0.1% difference from the RTX 4050 Mobile. The NVIDIA Quadro K6000 also scores 19030, again 0.1% behind. The NVIDIA Tesla K20m scores 19089, which is 0.2% ahead of the RTX 4050 Mobile. The NVIDIA RTX 2000 Ada Generation scores 18954, 0.5% behind. These results place the RTX 4050 Mobile in a tightly clustered performance band, where the differences between rivals are all within a fraction of a percent.

Ray tracing hardware also favors the Radeon, which has 40 RT cores versus 20 for the RTX 4050 Mobile. While both support DirectX 12 Ultimate, the Radeon's doubled RT core count suggests better ray-traced workload scaling. The RTX 4050 Mobile counters with 80 tensor cores, a feature entirely absent from the Radeon, giving NVIDIA the only dedicated path for AI-accelerated features.

Clock speed analysis reinforces the Radeon's compute advantage. The Radeon's 3000 MHz boost clock is 70.9% higher than the RTX 4050 Mobile's 1755 MHz boost. Even though the NVIDIA part starts at a higher base clock of 1455 MHz versus 1295 MHz, the Radeon's boost behavior dominates sustained performance. The Radeon's 55 W TDP is only 10% higher than the RTX 4050 Mobile's 50 W, meaning the AMD part delivers its substantial performance advantage at a modest power cost increase.

The memory situation remains the key uncertainty for the Radeon. Its system shared memory configuration means bandwidth is system dependent, so its real-world performance could vary significantly based on the host platform's memory speed and channel configuration. The RTX 4050 Mobile's fixed 192.0 GB/s bandwidth on 6 GB of GDDR6 provides a consistent, known memory performance that the Radeon cannot guarantee without specific system details.
