GPU Comparison

The NVIDIA Tesla P40 and AMD Radeon 8050S occupy opposite ends of the hardware spectrum, yet their average benchmark scores land within 4.6% of each other (65,095 vs 62,108). The Tesla P40 is a 2016-era, dual-slot PCIe accelerator built on Pascal, while the Radeon 8050S is a 2025 mobile integrated graphics processor (IGP) based on RDNA 3.5. Despite these generational and form-factor gaps, both cards achieve the 89th percentile among all GPUs, making them surprisingly close competitors in raw compute workloads. The data reveals a clear split: the AMD part wins OpenCL performance, while the NVIDIA part dominates Vulkan by a wide margin.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The NVIDIA Tesla P40 uses the GP102 chip based on the Pascal architecture, manufactured on a 16 nm process at TSMC. It packs 11,800 million transistors into a 471 mm² die, yielding a transistor density of 25.1 million per square millimeter. In contrast, the AMD Radeon 8050S uses the Strix Halo chip based on RDNA 3.5, fabricated on a more advanced 4 nm process at TSMC. Its die size is 308 mm², though AMD does not disclose its transistor count or density.

Shader core counts differ significantly. The Tesla P40 has 3,840 shading units, 240 texture mapping units (TMUs), and 96 ROPs. The Radeon 8050S has 2,048 shading units, 128 TMUs, and 64 ROPs, but it adds 32 ray tracing cores, hardware the Pascal-based Tesla P40 entirely lacks. Neither card includes tensor cores.

Memory architecture is a major divergence. The Tesla P40 features 24 GB of dedicated GDDR5 memory on a 384-bit bus, delivering 347.1 GB/s of bandwidth. The Radeon 8050S uses system-shared memory, meaning its capacity, type, bus width, and bandwidth are all system-dependent and not fixed specifications. This makes the Tesla P40 far more predictable for memory-bound workloads.

Clock speeds also reflect their different roles. The Tesla P40 runs at a 1303 MHz base and 1531 MHz boost, while the Radeon 8050S operates at 1295 MHz base but boosts aggressively to 2800 MHz. Pixel and texture rates are close: the Radeon 8050S achieves 179.2 GPixel/s versus 147.0 GPixel/s for the Tesla P40, while texture rates are 358.4 GTexel/s versus 367.4 GTexel/s.

Where Each One Wins

The AMD Radeon 8050S wins in OpenCL compute, scoring 65,818 versus 62,017 for the Tesla P40, a 5.8% advantage. This makes it the better choice for general-purpose compute workloads that rely on OpenCL, such as certain scientific simulations or media processing tasks. The Radeon 8050S also has a decisive advantage in power efficiency, with a 55 W TDP compared to the Tesla P40’s 250 W, and it requires no external power connectors. Its integrated nature means it fits in portable devices, and its PCIe 5.0 x16 interface provides double the bandwidth of the Tesla P40’s PCIe 3.0 x16.

The NVIDIA Tesla P40 wins decisively in Vulkan, scoring 68,172 versus 58,398 for the Radeon 8050S, a 16.7% margin. This suggests it handles Vulkan-based rendering and compute workloads substantially better. The Tesla P40 also offers 24 GB of dedicated GDDR5 memory, which is a fixed quantity, whereas the Radeon 8050S depends on system memory allocation. For workloads that need predictable, high-capacity VRAM without sharing system resources, the Tesla P40 is the safer bet. Its dual-slot design and 8-pin EPS power connector also indicate it is built for persistent, high-throughput server environments.

Specification Differences

The most obvious specification gap is in form factor and power. The Tesla P40 is a dual-slot, 267 mm long card requiring a 250 W TDP and an 8-pin EPS connector, with a suggested 600 W power supply. The Radeon 8050S is an IGP with a 55 W TDP, no power connectors, and no dedicated dimensions.

Memory is another key differentiator. The Tesla P40 has 24 GB GDDR5 on a 384-bit bus with 347.1 GB/s bandwidth. The Radeon 8050S uses system-shared memory with system-dependent bandwidth, so its memory specs are not fixed.

Shader resources differ: 3840 shading units, 240 TMUs, and 96 ROPs for the Tesla P40 versus 2048 shading units, 128 TMUs, and 64 ROPs for the Radeon 8050S. The Radeon 8050S adds 32 ray tracing cores, while the Tesla P40 has none.

The Radeon 8050S has a much higher boost clock (2800 MHz vs 1531 MHz) and a newer process node (4 nm vs 16 nm). The Tesla P40 has a slightly higher base clock (1303 MHz vs 1295 MHz).

Display outputs differ: the Tesla P40 has no outputs, while the Radeon 8050S is portable-device dependent. Bus interfaces are PCIe 3.0 x16 for the Tesla P40 and PCIe 5.0 x16 for the Radeon 8050S. The Tesla P40 is end-of-life with a launch MSRP of 5,699 USD, while the Radeon 8050S is active with no listed MSRP.

Head-to-Head Benchmarks

The two GPUs split their two Geekbench tests exactly one win apiece, but the margins tell very different stories. In Geekbench OpenCL, the AMD Radeon 8050S takes a 5.8% victory with a score of 65,818 against the Tesla P40’s 62,017. This is a modest but clear win, placing the Radeon 8050S in line with its nearest rival, the Radeon Pro W6600M, which sits just 0.3% slower. The Tesla P40, meanwhile, trails its closest competitor, the Radeon Pro WX 9100, by 1.4%, meaning the OpenCL result is consistent with the P40’s position in the broader market.

The Vulkan test flips the script dramatically. The NVIDIA Tesla P40 scores 68,172, which is 16.7% ahead of the Radeon 8050S’s 58,398. This is the largest delta in the entire head-to-head comparison, and it aligns with the Tesla P40’s rival set: its nearest Vulkan competitors include the AMD Radeon VII at 66,004 and the Radeon Pro WX 9100 at 64,212, both of which the P40 beats by 1.4% and 2% respectively. The Radeon 8050S, on the other hand, falls 2.5% to 2.7% short of its own nearest rivals (Radeon Pro Vega 56 and RX 7600M) in average score, and its Vulkan result is far below its OpenCL showing.

What the data shows is a GPU that wins with raw throughput (the Radeon 8050S’s higher boost clock and RDNA 3.5 efficiency) and a GPU that wins with driver maturity and architectural optimization for specific APIs (the Tesla P40’s Pascal design excelling in Vulkan). The average scores, 65,095 for the Tesla P40 and 62,108 for the Radeon 8050S, mask the fact that these are not interchangeable parts. One is a server accelerator with fixed memory and no display outputs; the other is a mobile IGP with shared memory and ray tracing support. The 16.7% Vulkan gap is the single most striking number in this comparison, dwarfing the 5.8% OpenCL difference and suggesting that API selection matters more than raw specifications when choosing between these two.
