AMD Radeon 8065S vs NVIDIA GeForce RTX 4090 D Comparison

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark comparisons between the AMD Radeon 8065S and the NVIDIA GeForce RTX 4090 D. However, the recorded data for the RTX 4090 D provides a clear reference point for its performance class. The RTX 4090 D achieved a 3DMark Steel Nomad DX12 score of 8,587, a Geekbench OpenCL score of 278,621, and a Geekbench Vulkan score of 246,941. Its average benchmark score across all recorded tests is 178,050, placing it in the 98th percentile of all GPUs in the database.

The Radeon 8065S has no recorded benchmark scores, an average benchmark score of zero, and sits at the 50th percentile. This places the Radeon 8065S in a fundamentally different performance tier based on the available data. The RTX 4090 D outperforms its nearest recorded rivals by measurable margins: it trails the NVIDIA RTX PRO 5000 Blackwell by 2.2%, the NVIDIA A100 SXM4 80 GB by 3.1%, the NVIDIA RTX 5000 Ada Generation by 3.6%, and the NVIDIA A100 SXM4 40 GB by 4.9%. These delta values confirm that the RTX 4090 D operates within a narrow band of high-end workstation and server-class GPUs, all scoring above 182,000 on average.

For the Radeon 8065S, the absence of any benchmark entries means the database cannot produce a quantitative comparison. The recorded specifications, however, indicate a compute ceiling far below the RTX 4090 D. The Radeon 8065S delivers 15.36 TFLOPS of FP32 performance, while the RTX 4090 D delivers 73.54 TFLOPS, a 4.8x difference in raw shader throughput. Texture rate shows a similar gap: 480.0 GTexel/s versus 1,149.1 GTexel/s. Pixel rate also favors NVIDIA substantially, at 192.0 GPixel/s versus 443.5 GPixel/s.

The RTX 4090 D also holds a decisive advantage in memory bandwidth at 1.01 TB/s, whereas the Radeon 8065S relies on system shared memory with bandwidth listed as system dependent. This makes the RTX 4090 D the clear winner in every measurable performance category present in the database. The Radeon 8065S, with its 50th percentile ranking and no scores, cannot be positioned against the RTX 4090 D in any benchmark-driven analysis.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon 8065S uses the Gorgon Halo chip based on RDNA 3.5, belongs to the Navi Mobile (RX 8000M) generation, and is built on a 4 nm process at TSMC. The die size is 308 mm². The NVIDIA GeForce RTX 4090 D uses the AD102 chip based on Ada Lovelace, belongs to the GeForce 40 generation, and is built on a 5 nm process, also at TSMC. Its die size is 609 mm², with 76,300 million transistors and a transistor density of 125.3M per mm². The Radeon 8065S lists transistor count as unknown.

Core configurations differ sharply. The Radeon 8065S has 2,560 shading units, 160 texture mapping units, 64 raster output units, and 40 ray tracing cores. It has no dedicated tensor cores listed. The RTX 4090 D has 14,592 shading units, 456 texture mapping units, 176 raster output units, 114 ray tracing cores, and 456 tensor cores. That represents 5.7x more shading units, 2.85x more TMUs, 2.75x more ROPs, and 2.85x more ray tracing cores.

Clock behavior also differs. The Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The RTX 4090 D has a base clock of 2280 MHz and a boost clock of 2520 MHz. Despite the lower absolute boost clock, the RTX 4090 D achieves far higher throughput due to its larger execution resource pool. The Radeon 8065S memory subsystem is entirely system shared, with no dedicated VRAM, bus width, or bandwidth figures. The RTX 4090 D uses 24 GB of GDDR6X memory on a 384-bit bus with 1.01 TB/s bandwidth and a memory clock of 1313 MHz (21 Gbps effective).

Power and physical characteristics diverge completely. The Radeon 8065S has a TDP of 55 W, is an integrated graphics processor (IGP) with no slot width, uses no power connectors, and is portable device dependent for display outputs. The RTX 4090 D has a TDP of 425 W, is triple-slot, requires a single 16-pin power connector, and suggests an 800 W power supply. The RTX 4090 D measures 304 mm in length, 137 mm in height, and 61 mm in width. The Radeon 8065S has no recorded dimensions.

Interface and API support show parity in some areas. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface differs: the Radeon 8065S uses PCIe 5.0 x16, while the RTX 4090 D uses PCIe 4.0 x16. Production status also differs, with the Radeon 8065S listed as active and the RTX 4090 D as end-of-life. The Radeon 8065S was released on 2025-12-31, while the RTX 4090 D was released on 2023-12-27.

Where Each One Wins

Based strictly on the recorded data, the NVIDIA GeForce RTX 4090 D wins every performance category. Its 73.54 TFLOPS FP32 throughput, 1,149.1 GTexel/s texture rate, and 443.5 GPixel/s pixel rate place it in the top 2% of all GPUs in the database. The 24 GB GDDR6X memory with 1.01 TB/s bandwidth supports large datasets and high-resolution rendering workloads without system memory contention. The 456 tensor cores provide dedicated hardware for AI and deep learning acceleration, a feature absent from the Radeon 8065S specification sheet.

The RTX 4090 D also wins in ray tracing capability, with 114 ray tracing cores versus 40 on the Radeon 8065S. The recorded 3DMark Steel Nomad DX12 score of 8,587 confirms strong DirectX 12 rasterization performance. Geekbench OpenCL and Vulkan scores of 278,621 and 246,941 respectively indicate broad compute and graphics API strength. Its nearest rivals all score within a 2.2% to 4.9% range, meaning the RTX 4090 D sits at the upper edge of a very competitive high-end segment.

The AMD Radeon 8065S wins in power efficiency by a wide margin. Its 55 W TDP is 7.7x lower than the 425 W TDP of the RTX 4090 D. It requires no external power connectors and fits as an integrated processor, making it suitable for portable devices where space and cooling are constrained. Its 3000 MHz boost clock is higher than the 2520 MHz boost clock of the RTX 4090 D, though this does not translate into higher throughput given the much smaller execution resource pool. The Radeon 8065S also uses PCIe 5.0 x16, a newer bus standard than the PCIe 4.0 x16 on the RTX 4090 D.

The Radeon 8065S has a smaller die at 308 mm² versus 609 mm², which typically correlates with lower manufacturing cost per wafer, though the database does not provide pricing for the AMD part. Its active production status and 2025 release date indicate a current-generation product, while the RTX 4090 D is end-of-life with a successor listed as GeForce 50.

The Verdict

The data presents a straightforward choice based on performance requirements. The NVIDIA GeForce RTX 4090 D is the only option for users who need maximum compute throughput, high-bandwidth dedicated memory, or extensive ray tracing resources. Its 98th percentile ranking, average benchmark score of 178,050, and proximity to workstation-class rivals like the RTX PRO 5000 Blackwell and A100 SXM4 variants make it a top-tier solution for demanding graphics and compute workloads. The 24 GB GDDR6X memory and 1.01 TB/s bandwidth support large model inference, high-resolution rendering, and data-intensive visualization tasks.

The AMD Radeon 8065S is the appropriate choice for ultra-mobile or power-constrained systems where a 55 W TDP and integrated form factor are mandatory. Its 50th percentile ranking and absence of benchmark scores mean it cannot be recommended for performance-critical applications based on the database. However, its 4 nm process, 3000 MHz boost clock, and PCIe 5.0 interface indicate a modern, efficient design suited for portable devices. The lack of dedicated memory limits its capability in memory-bound workloads.

Users requiring a discrete desktop GPU with established benchmark data should select the RTX 4090 D. Users building a thin-and-light system with an integrated processor should consider the Radeon 8065S, with the understanding that its performance ceiling is far lower. The RTX 4090 D holds a 4.8x advantage in FP32 throughput, a 2.4x advantage in texture rate, and a 2.3x advantage in pixel rate. These margins, combined with the dedicated tensor cores and larger memory subsystem, make the NVIDIA part the dominant choice for any workload where performance matters more than power draw.
