NVIDIA GeForce GTX TITAN X vs NVIDIA RTX A500 Mobile Comparison

Head-to-Head Benchmarks

The data presents a clear, if narrow, picture of two very different NVIDIA GPUs separated by seven years of architecture evolution. In the two shared benchmark tests — Geekbench OpenCL and Geekbench Vulkan — the older NVIDIA GeForce GTX TITAN X wins both, but the margin tells a more nuanced story than a simple sweep.

In Geekbench OpenCL, the GTX TITAN X scores 41,471 against the RTX A500 Mobile’s 41,263. That is a delta of only -0.5% from the mobile card’s perspective, effectively a statistical tie. The RTX A500 Mobile lands within 208 points of a desktop flagship from 2015, which is remarkable given the massive differences in power envelope and physical size. The GTX TITAN X pulls ahead decisively in Geekbench Vulkan, however, posting 49,397 versus 37,873 for the RTX A500 Mobile — a delta of -23.3%. That is a substantial gap, one that reflects the GTX TITAN X’s raw compute advantage in a modern API workload where the older card’s larger memory bus and higher shading unit count can flex.

The RTX A500 Mobile’s average benchmark score of 39,568 places it in the 82nd percentile of all GPUs, while the GTX TITAN X’s average of 36,530 sits at the 80th percentile. This is counterintuitive at first glance — the GTX TITAN X wins both head-to-head tests, yet its average score across all benchmarks is lower. That discrepancy stems from the GTX TITAN X’s additional Geekbench Metal score of 18,723, which drags its average down; the RTX A500 Mobile has no Metal result in the data. The nearest rivals for the RTX A500 Mobile include the AMD Radeon Pro 575 at 39,555 (0% delta), the AMD Radeon Pro 575X at 39,116 (1.2% delta), the AMD Radeon Pro WX 7100 at 40,063 (-1.2% delta), and the AMD Radeon Pro 580 at 40,318 (-1.9% delta). The GTX TITAN X’s nearest rivals are the AMD Radeon RX 5300M at 36,529 (0% delta), NVIDIA T1000 at 36,289 (0.7% delta), AMD Radeon PRO W6400 at 37,157 (-1.7% delta), and AMD Radeon Pro Duo at 35,860 (1.9% delta).

Looking at the head-to-head wins: the GTX TITAN X takes both, but the OpenCL result is too close to call as a meaningful victory. The Vulkan result is the differentiator. A -23.3% delta in Vulkan means the GTX TITAN X is roughly 30% faster in that specific workload — a decisive margin. Yet the RTX A500 Mobile’s higher average score and higher percentile indicate that, across a broader test suite, the mobile card holds its own or even surpasses the older desktop part in other scenarios not captured in this head-to-head set.

The Verdict

The data does not support a single winner across all contexts. The NVIDIA GeForce GTX TITAN X wins both head-to-head benchmarks, including a commanding Vulkan lead, and offers substantially more memory (12 GB versus 4 GB) and memory bandwidth (336.6 GB/s versus 96.00 GB/s). But the RTX A500 Mobile counters with a higher average benchmark score (39,568 versus 36,530), a higher percentile ranking (82nd versus 80th), and dramatically lower power consumption (30 W versus 250 W).

Who should pick the GTX TITAN X? Anyone whose workloads are dominated by Vulkan compute or who needs large memory capacity and high bandwidth for datasets that exceed 4 GB. The card’s 384-bit bus and 12 GB of GDDR5 deliver 336.6 GB/s — 3.5 times the bandwidth of the RTX A500 Mobile. That is an enormous practical advantage for texture-heavy or large-buffer workloads. The GTX TITAN X also has 3,072 shading units versus 2,048, 192 TMUs versus 64, and 96 ROPs versus 32, giving it raw throughput advantages that show up in the Vulkan score.

Who should pick the RTX A500 Mobile? Anyone constrained by power or physical space. The mobile card is an IGP (integrated graphics processor) with no power connectors and a 30 W TDP, versus a dual-slot, 250 W card requiring a 600 W suggested PSU and both a 6-pin and 8-pin connector. The RTX A500 Mobile also brings modern architecture features — Ampere with 16 ray tracing cores and 64 tensor cores — that the Maxwell-based GTX TITAN X lacks entirely. For a laptop or compact system, the GTX TITAN X is physically impossible; the RTX A500 Mobile is designed for exactly that form factor.

The verdict is situational. If the benchmark suite is Vulkan-heavy and memory capacity matters, the GTX TITAN X wins outright. If the context is mobile, power-constrained, or requires ray tracing or tensor operations, the RTX A500 Mobile is the only viable option despite losing the head-to-head tests.

Where Each One Wins

NVIDIA GeForce GTX TITAN X wins on: Vulkan compute (49,397 versus 37,873, a 23.3% margin), OpenCL (41,471 versus 41,263, a marginal 0.5% edge), memory capacity (12 GB versus 4 GB), memory bandwidth (336.6 GB/s versus 96.00 GB/s), pixel rate (104.5 GPixel/s versus 49.18 GPixel/s), texture rate (209.1 GTexel/s versus 98.37 GTexel/s), and raw FP32 throughput (6.691 TFLOPS versus 6.296 TFLOPS). The GTX TITAN X also has more shading units (3,072 versus 2,048), more TMUs (192 versus 64), and more ROPs (96 versus 32).

NVIDIA RTX A500 Mobile wins on: average benchmark score (39,568 versus 36,530), percentile ranking (82nd versus 80th), power efficiency (30 W versus 250 W), and architecture features. The Ampere architecture brings 16 ray tracing cores and 64 tensor cores, which the GTX TITAN X does not have at all. The RTX A500 Mobile also supports DirectX 12 Ultimate (12_2) versus the GTX TITAN X’s DirectX 12 (12_1), a meaningful feature gap for modern game and compute APIs. The mobile card is also fabricated on an 8 nm Samsung process versus 28 nm TSMC, which explains the transistor density difference: 43.5M transistors per mm² versus 13.3M per mm², despite similar total transistor counts (8,700 million versus 8,000 million).

In practical terms: the GTX TITAN X wins for desktop rendering, large-scale compute, and any workload that can leverage its massive memory bus. The RTX A500 Mobile wins for mobile workstations, ray-traced workloads, and any scenario where power draw or physical footprint is a constraint.

Architecture Differences

The two GPUs represent opposite ends of NVIDIA’s design philosophy across generations. The NVIDIA GeForce GTX TITAN X uses the GM200 chip on the Maxwell 2.0 architecture, fabricated on TSMC’s 28 nm process. It packs 8,000 million transistors into a 601 mm² die, yielding a transistor density of 13.3M per mm². The NVIDIA RTX A500 Mobile uses the GA107S chip on the Ampere architecture, fabricated on Samsung’s 8 nm process. It contains 8,700 million transistors in a 200 mm² die, achieving a density of 43.5M per mm² — over three times the density of the older chip. This is the clearest illustration of process advancement: similar transistor counts, but the newer chip fits them into one-third the silicon area.

The memory subsystems diverge sharply. The GTX TITAN X uses 12 GB of GDDR5 on a 384-bit bus with a 1753 MHz memory clock (7 Gbps effective), delivering 336.6 GB/s. The RTX A500 Mobile uses 4 GB of GDDR6 on a 64-bit bus with a 1500 MHz memory clock (12 Gbps effective), delivering 96.00 GB/s. The bus width difference is the dominant factor: 384-bit versus 64-bit is a 6:1 ratio, and while GDDR6 runs at higher effective speeds, it cannot compensate for that bus disparity.

Compute resources tell a similar story. The GTX TITAN X has 3,072 shading units, 192 TMUs, and 96 ROPs, yielding a pixel rate of 104.5 GPixel/s and a texture rate of 209.1 GTexel/s. The RTX A500 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs, yielding 49.18 GPixel/s and 98.37 GTexel/s. FP32 throughput is close — 6.691 TFLOPS for the GTX TITAN X versus 6.296 TFLOPS for the RTX A500 Mobile — because the mobile card’s higher boost clock (1537 MHz versus 1089 MHz) partially offsets its fewer cores. The GTX TITAN X has no FP16 support listed, while the RTX A500 Mobile offers FP16 at a 1:1 ratio with FP32.

Feature support is where the newer card pulls ahead. The RTX A500 Mobile includes 16 ray tracing cores and 64 tensor cores, supports DirectX 12 Ultimate (12_2), and uses a PCIe 4.0 x8 interface. The GTX TITAN X lacks RT and tensor cores, supports only DirectX 12 (12_1), and uses PCIe 3.0 x16. Both support OpenGL 4.6 and Vulkan 1.4. The GTX TITAN X has fixed display outputs (1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.2), while the RTX A500 Mobile’s outputs are portable-device dependent. The GTX TITAN X measures 267 mm in length, 111 mm in height, and 38 mm in width; the RTX A500 Mobile has no listed dimensions but is an IGP slot-width design, and the GTX TITAN X is dual-slot. The GTX TITAN X launched with an MSRP of 999 USD in March 2015; the RTX A500 Mobile has no listed launch MSRP and released in March 2022. Both are end-of-life products.
