AMD Radeon 8065S vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two workstation-class GPUs. The NVIDIA RTX 4500 Ada Generation posts an average benchmark score of 166,094 across Geekbench OpenCL and Vulkan tests, placing it in the 97th percentile of all GPUs in the database. The AMD Radeon 8065S, by contrast, holds a 50th percentile position with an average benchmark score of zero, meaning no comparable benchmark entries exist for it in the database. This absence of recorded scores for the AMD part makes direct mathematical comparison impossible, but the percentile gap alone is stark: 97 versus 50.

The RTX 4500's nearest rivals in the database provide context for its standing. It sits 0.5% above the NVIDIA RTX A5500, which scores 165,217, and 0.7% above the AMD Radeon PRO W7800 at 164,894. It trails the AMD Radeon Pro W6900X by 1.5%, which leads this cluster at 168,574, while outpacing the NVIDIA A100 PCIe 40 GB by 2.2% (162,504). These margins are narrow, indicating the RTX 4500 occupies a tightly contested performance tier. The AMD Radeon 8065S has no nearest rivals listed, so its competitive position cannot be established from the database records.

The individual Geekbench results for the RTX 4500 show 160,786 in OpenCL and 171,401 in Vulkan. The Vulkan score runs 6.6% higher than the OpenCL score, suggesting the architecture handles the Vulkan workload more efficiently. For the AMD Radeon 8065S, no such breakdown exists, leaving its API-specific behavior undocumented in the database. The wins tally reflects this imbalance: zero wins for the AMD part, zero for the NVIDIA part, as no head-to-head benchmark entries were recorded.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It belongs to the Navi Mobile (RX 8000M) generation and is an integrated graphics processor (IGP) with a slot width listed as IGP. The die measures 308 mm², with transistor count listed as unknown in the database. The NVIDIA RTX 4500 Ada Generation uses the AD103 chip on Ada Lovelace architecture, built on a 5 nm process also at TSMC. It belongs to the Workstation Ada generation and the GeForce 40-series family, shipping as a dual-slot add-in card measuring 245 mm in length and 112 mm in height. Its die is larger at 379 mm², and the database records 45,900 million transistors with a density of 121.1 million per mm².

Clock behavior differs significantly. The AMD part runs a base clock of 1295 MHz and boosts to 3000 MHz, a 131.7% increase from base to boost. The NVIDIA part starts at 2070 MHz base and boosts to 2580 MHz, a more modest 24.6% uplift. Despite the AMD part's higher boost clock, the NVIDIA part's raw compute resources dwarf it. The RTX 4500 carries 7680 shading units, 240 texture mapping units, 80 ROPs, 60 RT cores, and 240 tensor cores. The Radeon 8065S has 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores, with no tensor cores listed. The NVIDIA part also features tensor cores, which the AMD part lacks entirely in the database record.

Memory architecture is another major divergence. The AMD Radeon 8065S uses system shared memory, with size, type, bus width, and bandwidth all listed as system dependent. The NVIDIA RTX 4500 has 24 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth at 2250 MHz (18 Gbps effective). The AMD part's memory bandwidth is not quantified, only described as system dependent. This distinction matters for workstation workloads that rely on consistent, high-bandwidth local memory.

The manufacturing node difference is notable: 4 nm for AMD versus 5 nm for NVIDIA, both at TSMC. The smaller node gives AMD a potential density or efficiency advantage on paper, but the NVIDIA die packs nearly twice the shading units and roughly three times the transistor count. The power envelope reflects this: the AMD part is rated at 55 W TDP, while the NVIDIA part draws 210 W TDP with a suggested PSU of 550 W. The AMD part uses no power connectors as an IGP, while the NVIDIA part also lists no power connectors, relying on the PCIe slot plus auxiliary power in practice. The bus interface differs as well: PCIe 5.0 x16 for AMD versus PCIe 4.0 x16 for NVIDIA.

The Verdict

The data points to the NVIDIA RTX 4500 Ada Generation as the stronger performer by every recorded compute metric. Its FP32 throughput of 39.63 TFLOPS is 2.58 times the AMD part's 15.36 TFLOPS. Its texture rate of 619.2 GTexel/s exceeds the AMD part's 480.0 GTexel/s by 29.0%. Its pixel rate of 206.4 GPixel/s beats 192.0 GPixel/s by 7.5%. The RTX 4500 also carries 24 GB of dedicated GDDR6 memory at 432.0 GB/s, compared to the AMD part's system shared memory with no quantified bandwidth. The 97th percentile ranking versus the 50th percentile ranking underscores the gap in recorded benchmark performance.

The AMD Radeon 8065S has advantages in specific areas: a smaller 4 nm process node, a higher boost clock at 3000 MHz, a lower 55 W TDP, and PCIe 5.0 x16 connectivity. Its IGP form factor means no separate card is needed, which suits portable or space-constrained systems. The 308 mm² die is smaller than the NVIDIA part's 379 mm², and the absence of power connectors reflects its integrated nature.

For workstation workloads that demand raw compute, dedicated memory, and proven benchmark scores, the RTX 4500 Ada Generation is the clear choice based on the recorded data. Its nearest rivals cluster within 2.2%, but none displace it from the top of that group. The AMD part, with no benchmark entries and no nearest rivals, cannot be positioned relative to any competitor in the database. Its 55 W power draw and integrated design suggest a different use case, one where efficiency and compactness outweigh absolute performance. The 50th percentile ranking places it at the median of all GPUs, while the RTX 4500 sits at the 97th percentile, a 47-point spread that reflects a substantial performance chasm. Users requiring sustained compute throughput, large local memory pools, or Vulkan performance near 171,401 should favor the NVIDIA part. Users prioritizing a low-power integrated solution with a 3000 MHz boost clock may find the AMD part suitable, but the database provides no evidence of its real-world performance.
