AMD Radeon RX 5300M vs NVIDIA GeForce GTX TITAN X Comparison

# NVIDIA GeForce GTX TITAN X vs AMD Radeon RX 5300M

The NVIDIA GeForce GTX TITAN X and AMD Radeon RX 5300M sit at opposite ends of the GPU spectrum, yet their aggregate benchmark scores are nearly identical—36,530 versus 36,529, a 0.0% delta. This remarkable statistical tie, however, masks fundamentally different architectures, memory configurations, and intended use cases. The GTX TITAN X is a 2015 desktop flagship built on Maxwell 2.0 with a 250 W TDP, while the RX 5300M is a 2019 mobile part on RDNA 1.0 with an 85 W TDP. Their shared 80th percentile ranking among all GPUs means both outperform the majority of the field, but they achieve this parity through entirely different design philosophies.

Where Each One Wins

The GTX TITAN X wins the only direct head-to-head benchmark available, the Geekbench OpenCL test, with a score of 41,471 against the RX 5300M's 36,529—a 13.5% advantage. This desktop card also holds a significant edge in raw compute throughput, delivering 6.691 TFLOPS of FP32 performance versus the mobile AMD part's 4.069 TFLOPS. The TITAN X further dominates in memory bandwidth at 336.6 GB/s compared to 168.0 GB/s, and its 12 GB GDDR5 frame buffer is four times larger than the RX 5300M's 3 GB GDDR6 allocation.

The RX 5300M wins in efficiency and portability. Its 85 W TDP is less than one-third of the TITAN X's 250 W, and it requires no power connectors—drawing everything from the PCIe slot—whereas the TITAN X demands a 1x 6-pin plus 1x 8-pin configuration and a 600 W suggested PSU. The RDNA 1.0 architecture also gives it a distinct FP16 advantage: 8.138 TFLOPS (2:1) versus no FP16 capability listed for Maxwell 2.0. For users prioritizing battery life, thermals, and physical footprint in a laptop chassis, the RX 5300M is the clear choice. For desktop users needing maximum FP32 throughput and memory capacity, the TITAN X wins decisively.

FAQ

Q: What are the power requirements for each card?

A: The TITAN X has a 250 W TDP, requires a 1x 6-pin plus 1x 8-pin power connector, and suggests a 600 W PSU. The RX 5300M has an 85 W TDP and needs no power connectors.

Q: Which GPU is more transistor-dense?

A: The RX 5300M's Navi 14 chip packs 6,400 million transistors into 158 mm², yielding a density of 40.5M per mm². The TITAN X's GM200 die is 601 mm² with 8,000 million transistors, giving 13.3M per mm².

Head-to-Head Benchmarks

The sole head-to-head benchmark result is the Geekbench OpenCL test, where the GTX TITAN X delivers 41,471 points against the RX 5300M's 36,529. That 13.5% delta is substantial and reflects the TITAN X's overwhelming hardware advantage in shading units, texture units, and memory bandwidth. The TITAN X fields 3,072 shading units, 192 TMUs, and 96 ROPs, while the RX 5300M offers 1,408 shading units, 88 TMUs, and just 32 ROPs. This 2.2x difference in shading units and 3x difference in ROPs directly explains the OpenCL performance gap.

The TITAN X also posts higher pixel and texture fill rates: 104.5 GPixel/s and 209.1 GTexel/s versus the RX 5300M's 46.24 GPixel/s and 127.2 GTexel/s. These are not close figures. The TITAN X more than doubles the pixel throughput and exceeds the texture rate by 64%. Even with the RX 5300M's higher boost clock—1445 MHz versus 1089 MHz—the massive core count disparity cannot be overcome. The RX 5300M's 4.069 TFLOPS of FP32 compute is only 61% of the TITAN X's 6.691 TFLOPS.

What makes the near-identical average scores remarkable is that the RX 5300M has no other benchmark results in the data beyond the OpenCL test. Its 36,529 average comes from that single run, while the TITAN X's 36,530 average includes Geekbench Metal (18,723), OpenCL (41,471), and Vulkan (49,397) results. The TITAN X's OpenCL score is its middle result, with Vulkan showing a 19% improvement over OpenCL and Metal lagging by 55%. The RX 5300M lacks Vulkan and Metal scores, so its average may not be directly comparable across all workloads.

Specification Differences

The two GPUs differ in nearly every measurable specification. Memory size: 12 GB versus 3 GB. Memory type: GDDR5 versus GDDR6. Bus width: 384-bit versus 96-bit. Bandwidth: 336.6 GB/s versus 168.0 GB/s. Shading units: 3,072 versus 1,408. TMUs: 192 versus 88. ROPs: 96 versus 32. Pixel rate: 104.5 GPixel/s versus 46.24 GPixel/s. Texture rate: 209.1 GTexel/s versus 127.2 GTexel/s. FP32: 6.691 TFLOPS versus 4.069 TFLOPS.

Clock speeds also diverge. The TITAN X runs at a 1000 MHz base and 1089 MHz boost, with memory at 1753 MHz (7 Gbps effective). The RX 5300M has a 1000 MHz base, 1181 MHz game clock, 1445 MHz boost, and memory at 1750 MHz (14 Gbps effective). The RX 5300M's higher boost clock partially compensates for fewer cores, but the memory bandwidth difference remains stark—the TITAN X moves data at twice the rate despite slower GDDR5, thanks to its 4x wider bus.

Power and physical specs differ completely. The TITAN X is a dual-slot, 267 mm long desktop card (10.5 inches), 111 mm tall, 38 mm wide, with a 250 W TDP and 600 W suggested PSU. The RX 5300M has no listed dimensions, consumes 85 W, and requires no power connectors—it is a mobile part with output options described as "Portable Device Dependent." The TITAN X offers 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2 outputs; the RX 5300M's outputs are entirely dependent on the host laptop.

Architecture Differences

The architectural divide is generational. The TITAN X uses NVIDIA's Maxwell 2.0 architecture on the GM200 chip, built on TSMC's 28 nm process. The die is massive at 601 mm², housing 8,000 million transistors at a density of 13.3M per mm². The RX 5300M employs AMD's RDNA 1.0 on the Navi 14 chip, fabricated on TSMC's 7 nm node. Its die is just 158 mm² but packs 6,400 million transistors, achieving a 40.5M per mm² density—three times higher than Maxwell 2.0.

These process differences explain the efficiency gap. The 28 nm TITAN X needs 250 W to sustain its clocks, while the 7 nm RX 5300M delivers 61% of its FP32 throughput at only 34% of the power draw. The RDNA 1.0 architecture also introduces FP16 support at a 2:1 ratio (8.138 TFLOPS), which Maxwell 2.0 lacks entirely. This makes the RX 5300M better suited for workloads leveraging mixed-precision computing, despite its overall lower FP32 peak.

The TITAN X belongs to the GeForce 900 generation with a predecessor in GeForce 700 and successor in GeForce 10. The RX 5300M is part of the Radeon RX 5000 series under the Navi Mobile (RX 5000M) generation, succeeding Polaris Mobile with no listed successor. Both are end-of-life products. The TITAN X launched on March 16, 2015 with a launch MSRP of 999 USD. The RX 5300M arrived nearly five years later on November 12, 2019, with no launch MSRP recorded. The TITAN X uses PCIe 3.0 x16, while the RX 5300M uses PCIe 4.0 x8—the newer standard offering double the per-lane bandwidth but half the lane count. Neither card supports ray tracing or tensor cores, and both expose identical API feature levels: DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.
