AMD Radeon Pro 5300M vs NVIDIA Tesla C2075 Comparison

NVIDIA's Tesla C2075 and AMD's Radeon Pro 5300M represent two distinct eras of GPU design, separated by nearly a decade of architectural evolution. The data shows a clear generational gap, with the AMD part dominating the only shared benchmark while the NVIDIA card relies on its legacy compute credentials. This analysis breaks down the head-to-head results, architectural philosophies, and specification differences to determine which GPU holds up better in a modern context.

Head-to-Head Benchmarks

The single directly comparable benchmark in the data is Geekbench OpenCL, and the result is decisively one-sided. The AMD Radeon Pro 5300M scores 29,252, while the NVIDIA Tesla C2075 manages 10,400. That translates to a deltaPct of -64.4% for the NVIDIA card, meaning the AMD part is approximately 181% faster in this compute workload. The margin is enormous, reflecting not just clock speed advantages but a fundamentally more efficient architecture.

To contextualize the Tesla C2075's score, its nearest rivals in the database are telling. The AMD Radeon RX 6500M scores 10,362, a mere 0.4% higher, and the NVIDIA GeForce GTX 950A scores 10,273, which is 1.2% lower. The Tesla C2075 sits at the 48th percentile of all GPUs, placing it in the mid-range of historical performance. Its OpenCL result of 10,400 places it within a tight cluster of older mobile and entry-level desktop parts, none of which approach the Radeon Pro 5300M's output.

The Radeon Pro 5300M, by contrast, achieves its 29,252 OpenCL score while also sitting at the 48th percentile overall. Its nearest rivals include the NVIDIA Quadro K5100M at 10,043 (a -0.3% delta) and the NVIDIA GeForce GTX 870M at 9,959 (a 0.5% delta). The fact that the AMD part's nearest rivals are all in the 10,000-point range, yet its own score is nearly triple that, indicates the percentile ranking is heavily weighted by a broad field of modern GPUs that vastly outperform both cards. The Radeon Pro 5300M also shows versatility in other APIs, with a Geekbench Metal score of 33,626 and a Vulkan score of 27,912, though NVIDIA's card lacks comparable entries for those tests.

In a straight compute comparison, the Radeon Pro 5300M wins the only head-to-head test, and it wins by a landslide. The Tesla C2075 does not have a single benchmark victory in this dataset, with winsA at 0 and winsB at 1. This is not a close contest; it is a generational wipeout.

The Verdict

The data unequivocally favors the AMD Radeon Pro 5300M for any modern compute or graphics workload. Its OpenCL score of 29,252 is nearly three times that of the Tesla C2075's 10,400, and it offers additional API support including Vulkan 1.4 and DirectX 12 (12_1), whereas the NVIDIA card is limited to DirectX 12 (11_0) with no Vulkan support. For users running OpenCL-based applications, the choice is obvious: the Radeon Pro 5300M delivers vastly superior throughput.

The NVIDIA Tesla C2075 retains relevance only in legacy contexts. Its Fermi architecture, with a 40 nm process and 3,000 million transistors, was designed for a different era of scientific computing. Its 6 GB of GDDR5 memory on a 384-bit bus provides 150.3 GB/s of bandwidth, which was substantial in 2011 but is now dwarfed by the Radeon's 192.0 GB/s from a 128-bit GDDR6 interface. The Tesla's dual-slot design and 247 W TDP also make it a power-hungry, physically imposing card compared to the Radeon's 85 W TDP and compact mobile footprint.

Who should pick which? Strictly from the data, the Radeon Pro 5300M is the superior choice for anyone prioritizing raw compute performance, modern API compatibility, or energy efficiency. The Tesla C2075 is only defensible for users maintaining legacy systems that require its specific PCIe 2.0 x16 interface or its 6 GB memory capacity, which exceeds the Radeon's 4 GB. However, even that advantage is mitigated by the Radeon's higher bandwidth and faster memory technology. The verdict is clear: the Radeon Pro 5300M wins on performance, efficiency, and feature support.

Architecture Differences

The architectural gap between these two GPUs is vast. The NVIDIA Tesla C2075 is built on the Fermi 2.0 architecture, using the GF110 chip fabricated on a 40 nm process at TSMC. Fermi was NVIDIA's second-generation unified shader architecture, and the GF110 die is massive at 520 mm², housing 3,000 million transistors. This results in a transistor density of just 5.8 million per square millimeter, a figure that reflects the larger, less dense design rules of early 2010s manufacturing.

In contrast, the AMD Radeon Pro 5300M uses the RDNA 1.0 architecture with the Navi 14 chip, also built at TSMC but on a 7 nm process. The Navi 14 die is just 158 mm², yet it packs 6,400 million transistors, achieving a density of 40.5 million per square millimeter. That is nearly seven times the transistor density of the Fermi chip, enabling far more compute units in a smaller physical footprint. RDNA 1.0 was AMD's first generation of the Radeon DNA architecture, designed for high efficiency and scalable performance across desktop and mobile parts.

The functional units tell the same story. The Tesla C2075 has 448 shading units, 56 texture mapping units, and 48 ROPs. The Radeon Pro 5300M has 1,280 shading units, 80 TMUs, and 32 ROPs. While the NVIDIA card has more ROPs, the AMD card's superior shader count and TMU count drive its much higher pixel rate of 40.00 GPixel/s versus 16.07 GPixel/s, and texture rate of 100.0 GTexel/s versus 32.14 GTexel/s. The Radeon also supports FP16 compute at 6.400 TFLOPS with a 2:1 ratio, whereas the Tesla has no FP16 capability listed. This makes the Radeon far more flexible for mixed-precision workloads.

Specification Differences

The specification sheet reveals a comprehensive generational upgrade. The Tesla C2075 operates with a memory clock of 783 MHz (3.1 Gbps effective), while the Radeon Pro 5300M uses a 1500 MHz memory clock (12 Gbps effective). The Tesla offers 6 GB of GDDR5 on a 384-bit bus, delivering 150.3 GB/s, whereas the Radeon offers 4 GB of GDDR6 on a 128-bit bus, delivering 192.0 GB/s. The Radeon's narrower bus is compensated by faster memory, resulting in higher overall bandwidth.

Clock speeds are another differentiator. The Tesla C2075 has no listed base or boost clock, only its memory clock. The Radeon Pro 5300M has a base clock of 1000 MHz and a boost clock of 1250 MHz. This difference, combined with the architectural efficiency of RDNA, explains the massive performance gap. The Tesla's FP32 performance is 1,027.7 GFLOPS (approximately 1.03 TFLOPS), while the Radeon's FP32 is 3.200 TFLOPS, more than triple.

Power and physical specifications diverge sharply. The Tesla C2075 has a TDP of 247 W, requires a dual-slot cooler, and uses 1x 6-pin + 1x 8-pin power connectors, with a suggested PSU of 550 W. It measures 248 mm (9.8 inches) in length and has a single DVI display output. The Radeon Pro 5300M has a TDP of just 85 W, requires no external power connectors, and is described as "Portable Device Dependent" for display outputs, reflecting its mobile design. The Radeon uses a PCIe 4.0 x8 interface, while the Tesla uses PCIe 2.0 x16. Both cards are end-of-life, but their release dates are telling: the Tesla launched on 2011-07-24, while the Radeon launched on 2019-11-12, an 8-year gap.
