AMD Radeon Pro 5300 vs NVIDIA GeForce GTX TITAN X Comparison

The AMD Radeon Pro 5300 and NVIDIA GeForce GTX TITAN X represent two very different eras of GPU design, yet their average benchmark scores place them surprisingly close in overall performance. The Radeon Pro 5300, a 7nm RDNA 1.0 part from 2020, averages 40,870 points across Geekbench tests, while the older 28nm Maxwell-based GTX TITAN X from 2015 averages 36,530 points. This translates to an 82nd percentile ranking for the AMD card versus an 80th percentile for NVIDIA, showing that the modern architecture's efficiency nearly offsets the older card's massive physical advantage in raw resources. The data reveals a fascinating generational clash where workload-specific strengths diverge sharply.

Head-to-Head Benchmarks

The single most dramatic result in this comparison comes from the Geekbench Metal test, where the AMD Radeon Pro 5300 posts a score of 48,070 against the GTX TITAN X's 18,723. That is a 156.7% advantage for the AMD card, a staggering margin that suggests the RDNA 1.0 architecture has a decisive edge in Apple's Metal API environment. This is not a minor victory; it is a complete rout, indicating that the Radeon Pro 5300's design is far better optimized for Metal workloads than the older Maxwell part.

However, the tables turn completely when moving to other APIs. In Geekbench OpenCL, the GTX TITAN X scores 41,471 compared to the Radeon Pro 5300's 38,747, giving NVIDIA a 6.6% lead. The margin is modest but consistent, showing that the older card's higher shading unit count (3072 versus 1280) and wider memory bus (384-bit versus 128-bit) still translate to real compute advantages in OpenCL contexts. The GTX TITAN X's lead grows even larger in Geekbench Vulkan, where it scores 49,397 against 35,793 for the AMD card — a 27.5% gap that represents the NVIDIA card's best showing.

Looking at the aggregate picture, the head-to-head tally favors NVIDIA with 2 wins out of 3 tests, but the magnitude of the AMD victory in Metal outweighs the combined margins of the NVIDIA wins. The average benchmark score difference of 4,340 points (40,870 vs 36,530) amounts to roughly an 11% overall advantage for the Radeon Pro 5300, despite losing two of three individual tests. This suggests the Metal score heavily skews the average, and the "true" performance relationship depends entirely on which API matters most for a given application.

FAQ

Architecture Differences

The fundamental architectural gap between these two cards is enormous, starting with the manufacturing process. The Radeon Pro 5300 uses a 7nm TSMC process, while the GTX TITAN X relies on a 28nm TSMC process — a difference that explains the Radeon's far higher transistor density of 40.5 million transistors per square millimeter versus 13.3 million for the NVIDIA chip. The AMD card fits 6,400 million transistors into a 158 mm² die, while the GTX TITAN X packs 8,000 million transistors into a massive 601 mm² die. This density advantage is the core reason the Radeon Pro 5300 achieves comparable average performance with far fewer resources.

The compute architectures themselves diverge completely. AMD employs RDNA 1.0 with the Navi 14 chip, while NVIDIA uses Maxwell 2.0 with the GM200 chip. The Radeon Pro 5300 has 1280 shading units, 80 TMUs, and 32 ROPs, whereas the GTX TITAN X features 3072 shading units, 192 TMUs, and 96 ROPs. Despite having less than half the shading units, the Radeon Pro 5300 achieves a pixel rate of 52.80 GPixel/s and texture rate of 132.0 GTexel/s, compared to the GTX TITAN X's 104.5 GPixel/s and 209.1 GTexel/s. The clock speeds tell a similar story: both cards have a 1000 MHz base clock, but the Radeon boosts to 1650 MHz versus the GTX TITAN X's 1089 MHz.

The memory subsystems reflect different design priorities. The Radeon Pro 5300 uses 4GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s bandwidth at 14 Gbps effective. The GTX TITAN X offers 12GB of GDDR5 on a 384-bit bus, achieving 336.6 GB/s at 7 Gbps effective. The NVIDIA card's 50% higher bandwidth and 3x capacity come at the cost of older memory technology, while the Radeon's newer GDDR6 operates at double the effective speed. Neither card supports ray tracing or tensor cores, as both predate those features in their respective lineups.

Specification Differences

The most striking specification difference is power consumption. The Radeon Pro 5300 draws 85W TDP and is an integrated graphics processor (IGP) with no power connectors and a suggested 250W PSU. The GTX TITAN X demands 250W TDP, requires a dual-slot cooler, needs 1x 6-pin + 1x 8-pin power connectors, and suggests a 600W PSU. This nearly 3x power gap highlights the efficiency revolution between 2015 and 2020.

Memory capacity and type differ as well: 4GB GDDR6 versus 12GB GDDR5. The bus widths are 128-bit versus 384-bit, though the Radeon's faster memory clocks partially compensate. The GTX TITAN X has a PCIe 3.0 x16 interface, while the Radeon Pro 5300 uses PCIe 4.0 x8, which offers similar bandwidth on newer platforms. The GTX TITAN X provides display outputs (1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.2), while the Radeon Pro 5300 has no outputs at all, indicating its intended role as an embedded or Mac-specific part.

Physical dimensions differ dramatically: the GTX TITAN X measures 267mm in length, 111mm in height, and 38mm in width, while the Radeon Pro 5300's dimensions are not specified due to its IGP form factor. The release dates span five years apart — March 2015 for the GTX TITAN X and August 2020 for the Radeon Pro 5300. The GTX TITAN X had a launch MSRP of 999 USD, while the Radeon Pro 5300 has no listed launch MSRP. The GTX TITAN X's predecessor is GeForce 700 and successor is GeForce 10, while the Radeon Pro 5300 has no listed predecessor or successor.

Where Each One Wins

The AMD Radeon Pro 5300 is the clear winner in Metal-based workflows, where its 156.7% advantage over the GTX TITAN X makes it the only sensible choice for applications that leverage Apple's graphics API. Its 82nd percentile ranking and higher average score (40,870 vs 36,530) also make it the better all-around performer in aggregate benchmarks. The card's 7nm process and 85W TDP make it suitable for compact, power-constrained systems, particularly given its IGP form factor and lack of external power requirements. The Radeon Pro 5300's nearest rivals include the RTX 3080 Ti and RTX 5070, placing it in surprisingly modern company despite its professional Mac focus.

The NVIDIA GeForce GTX TITAN X wins in OpenCL and Vulkan environments, with its 6.6% OpenCL lead and 27.5% Vulkan advantage showing clear superiority in those APIs. Its 12GB memory capacity and 336.6 GB/s bandwidth make it preferable for memory-intensive workloads that exceed the Radeon Pro 5300's 4GB limit. The GTX TITAN X's dual-slot design and display outputs allow it to function as a standalone graphics card for gaming or workstation use, whereas the Radeon Pro 5300 cannot output video. Its 80th percentile ranking and exact performance match with the Radeon RX 5300M show it remains competitive even against newer parts.

The Verdict

The data paints a clear picture of two cards optimized for different worlds. The AMD Radeon Pro 5300 is the superior choice for Metal-centric environments, offering a 156.7% performance advantage that dwarfs any other metric in this comparison. Its 11% higher average benchmark score, 82nd percentile ranking, and dramatically lower power draw (85W vs 250W) make it the better all-around GPU for modern, efficiency-focused systems. The 7nm architecture and GDDR6 memory demonstrate how far GPU technology progressed in five years, achieving competitive average performance with a fraction of the silicon area.

The NVIDIA GeForce GTX TITAN X remains the pick for Vulkan and OpenCL workloads, where its 27.5% and 6.6% leads respectively show that raw compute resources still matter in those APIs. Its 12GB memory capacity and 336.6 GB/s bandwidth are significant advantages for large datasets, and its dual-slot design with display outputs makes it a functional standalone card. The 999 USD launch MSRP reflects its original flagship positioning, though the data shows its performance has aged into the 80th percentile — respectable but no longer elite.

For users who prioritize Metal performance, the Radeon Pro 5300 is the only logical choice given its massive lead. For those working in OpenCL or Vulkan, the GTX TITAN X offers meaningful advantages. The Radeon Pro 5300's nearest rival is the RTX 3080 Ti (0.8% behind), while the GTX TITAN X matches the RX 5300M exactly, suggesting the AMD card competes with much newer hardware while the NVIDIA card has settled into a lower performance tier. Ultimately, the Radeon Pro 5300 wins on average performance and efficiency, but the GTX TITAN X's API-specific strengths make it the better tool for particular jobs.
