AMD Radeon 8065S vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Where Each One Wins

The benchmark data places both the AMD Radeon 8065S and the NVIDIA RTX PRO 4500 Blackwell Server at the 50th percentile among all GPUs, with average benchmark scores of zero in the recorded database. Neither part shows a head-to-head benchmark advantage over the other, and neither has recorded wins in any comparison category. The absence of measured performance data means the division of strengths must be drawn from the architectural and specification records rather than from synthetic or application test results.

The AMD Radeon 8065S occupies the mobile integrated graphics space. It is an IGP-class part built on the RDNA 3.5 architecture with a 4 nm process from TSMC. Its die size is 308 mm², and it ships with 2560 shading units, 160 texture mapping units, and 64 render output units. The boost clock reaches 3000 MHz from a 1295 MHz base. Power draw is listed at 55 W, and the slot width is recorded as IGP, meaning it is designed to be embedded within a portable device rather than installed as a discrete expansion card. The display outputs are described as portable device dependent, which reinforces its role as a component for laptops or other compact systems. It uses system-shared memory, with bandwidth dependent on the host platform.

The NVIDIA RTX PRO 4500 Blackwell Server is a different class entirely. It is a discrete, single-slot server accelerator built on the Blackwell 2.0 architecture with a 5 nm TSMC process. The chip, GB203, contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per mm². It has 10,496 shading units, 328 TMUs, and 112 ROPs. The boost clock is 2415 MHz from a 1215 MHz base. It carries 32 GB of GDDR7 memory on a 256-bit bus, with 800.3 GB/s of bandwidth. Power consumption is 165 W, delivered through a single 16-pin connector. The card is 267 mm long, 111 mm high, and 40 mm wide, with no display outputs, confirming its purpose as a compute-only server part.

The primary split is use case. The Radeon 8065S delivers graphics capability inside a power-constrained mobile platform. The RTX PRO 4500 Blackwell Server delivers high-throughput compute in a rack environment. The data shows no overlap in physical design, memory strategy, or thermal envelope.

Architecture Differences

The two GPUs diverge at the process level. The AMD part uses a 4 nm TSMC node, while the NVIDIA part uses a 5 nm TSMC node. Despite the larger node, the NVIDIA chip packs substantially more transistors: 45,600 million versus an unknown count for the AMD part. The die sizes are relatively close at 308 mm² for AMD and 378 mm² for NVIDIA, but the transistor density tells the story. NVIDIA reaches 120.6 million transistors per mm², while AMD does not disclose a density figure.

Core counts differ sharply. The Radeon 8065S has 2560 shading units, 160 TMUs, and 64 ROPs. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, and 112 ROPs. That is roughly four times the shading units and more than double the texture and render output resources. Ray tracing hardware also differs: AMD lists 40 ray tracing cores, while NVIDIA lists 82. NVIDIA additionally includes 328 tensor cores, a resource AMD does not record at all.

Clock behavior runs in opposite directions. The AMD part boosts to 3000 MHz, which is higher than the NVIDIA boost of 2415 MHz. But the NVIDIA chip starts from a lower 1215 MHz base versus AMD's 1295 MHz base. The higher AMD boost does not compensate for the massive difference in execution resources. Raw throughput figures confirm this. The AMD part delivers 15.36 TFLOPS of FP32 and FP16, with a 1:1 ratio between the two. The NVIDIA part delivers 50.70 TFLOPS of FP32 and FP16, also at 1:1. NVIDIA holds a 3.3x advantage in floating-point throughput. Pixel rate favors NVIDIA at 270.5 GPixel/s versus 192.0 GPixel/s, and texture rate favors NVIDIA at 792.1 GTexel/s versus 480.0 GTexel/s.

Memory architecture is the most fundamental split. The Radeon 8065S uses system-shared memory with a system-dependent bus width and bandwidth. The RTX PRO 4500 uses dedicated 32 GB of GDDR7 on a 256-bit bus with 800.3 GB/s of bandwidth. The AMD part cannot claim a fixed memory bandwidth figure because it depends entirely on the host platform. The NVIDIA part has a fixed, measurable memory subsystem.

Physical and power characteristics follow the architectural split. The AMD part is an IGP with no power connectors and a 55 W TDP. The NVIDIA part is a single-slot card with a 1x 16-pin connector, a 165 W TDP, and a suggested PSU of 450 W. Both use PCIe 5.0 x16 as the bus interface, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The release dates also differ. The AMD Radeon 8065S is recorded with a release date of 2025-12-31, while the NVIDIA RTX PRO 4500 is dated 2026-03-16. Both are marked as Active in production status. The AMD predecessor is Polaris Mobile, while the NVIDIA predecessor is Server Hopper. The NVIDIA successor is listed as Server Rubin.

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries between these two parts. There are no wins recorded for either side, and the average benchmark score for both is zero. The percentile ranking is identical at 50 for both. This means the comparison must rely on the specification deltas, which are substantial in nearly every compute category.

The FP32 throughput difference is the clearest measurable gap. The RTX PRO 4500 delivers 50.70 TFLOPS, which is 3.3 times the 15.36 TFLOPS of the Radeon 8065S. The FP16 numbers match the FP32 numbers on both parts due to the 1:1 ratio, so the same 3.3x advantage applies to half-precision workloads. Texture rate shows a 1.65x advantage for NVIDIA, at 792.1 GTexel/s versus 480.0 GTexel/s. Pixel rate shows a 1.41x advantage, at 270.5 GPixel/s versus 192.0 GPixel/s.

Ray tracing resources also favor NVIDIA, with 82 RT cores versus 40. Tensor core availability is exclusive to NVIDIA, with 328 units present on the RTX PRO 4500 and no equivalent listed for the AMD part. Memory bandwidth is not directly comparable because the AMD part has no fixed figure, but the NVIDIA part records 800.3 GB/s from GDDR7 on a 256-bit bus. The AMD part's memory bandwidth is listed as system dependent.

The boost clock is the one specification where AMD leads. The Radeon 8065S reaches 3000 MHz, which is 585 MHz higher than the NVIDIA boost of 2415 MHz. The AMD base clock of 1295 MHz is also 80 MHz higher than the NVIDIA base of 1215 MHz. This clock advantage does not translate into a throughput advantage because the NVIDIA part has far more execution units.

Power efficiency is a more complex comparison. The AMD part uses 55 W, while the NVIDIA part uses 165 W. That is a 3x difference in power draw. However, the NVIDIA part delivers 3.3x the FP32 throughput, so the performance per watt in FP32 is roughly similar when comparing the raw figures. The NVIDIA part also carries 32 GB of dedicated GDDR7 memory, which the AMD part cannot match with system-shared memory.

The Verdict

The data directs each GPU to a distinct deployment. The AMD Radeon 8065S fits in a portable device with a 55 W power budget, no external power connector, and system-shared memory. Its 15.36 TFLOPS of FP32 throughput and 3000 MHz boost clock serve integrated graphics workloads within the constraints of a mobile platform. It records no discrete memory bandwidth, no tensor cores, and no display outputs beyond what the host portable device provides.

The NVIDIA RTX PRO 4500 Blackwell Server is a compute accelerator for server racks. It requires a 450 W suggested PSU, uses a single 16-pin power connector, and measures 267 mm by 111 mm by 40 mm. Its 50.70 TFLOPS of FP32 throughput, 82 RT cores, 328 tensor cores, and 800.3 GB/s of GDDR7 bandwidth position it for dedicated compute tasks that demand fixed, high-bandwidth memory and massive parallel throughput. It has no display outputs, confirming it is not intended for graphics presentation.

The decision between the two is dictated by the platform. The Radeon 8065S is an IGP with no slot width, no power connectors, and portable-device-dependent outputs. It cannot be installed in a desktop or server chassis as a discrete component. The RTX PRO 4500 is a single-slot card with a fixed memory subsystem and server-oriented physical dimensions. It cannot serve as an integrated graphics solution for a laptop. The recorded data shows no overlap in form factor, memory strategy, or thermal envelope, so there is no scenario where both parts are viable alternatives for the same system.

The identical 50th percentile ranking and zero benchmark scores reflect the absence of measured results in the database, not equivalence in capability. The specification deltas are decisive: NVIDIA leads in shading units, TMUs, ROPs, RT cores, tensor cores, FP32, FP16, pixel rate, texture rate, memory capacity, memory type, memory bus width, and memory bandwidth. AMD leads in boost clock, base clock, and power draw. The architectural records indicate that the NVIDIA part is the higher-throughput compute device, while the AMD part is the lower-power integrated solution.
