Q: What is the transistor density comparison?

A: The AMD Radeon RX 7900 GRE, built on a 5 nm process, has a transistor density of 109.1M per mm². The NVIDIA GeForce GTX TITAN X, using a 28 nm process, has a density of 13.3M per mm², an 8.2-fold difference that highlights the manufacturing process gap.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The NVIDIA GeForce GTX TITAN X uses the GM200 chip based on Maxwell 2.0 architecture, fabricated by TSMC on a 28 nm process node. This older design contains 8,000 million transistors on a 601 mm² die, resulting in a transistor density of 13.3M per mm². In contrast, the AMD Radeon RX 7900 GRE uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito. It is also built by TSMC but on a much newer 5 nm process, packing 57,700 million transistors into a 529 mm² die, achieving a density of 109.1M per mm².

The core configurations diverge sharply. The TITAN X has 3072 shading units, 192 TMUs, and 96 ROPs. The RX 7900 GRE scales this up to 5120 shading units, 320 TMUs, and 160 ROPs. Notably, the RX 7900 GRE introduces 80 ray tracing cores, a feature entirely absent from the Maxwell 2.0-based TITAN X. Clock speeds also differ: the TITAN X operates at a base of 1000 MHz and boost of 1089 MHz, while the RX 7900 GRE runs at a base of 1287 MHz, a game clock of 1880 MHz, and a boost of 2245 MHz.

Memory architecture represents another major divergence. The TITAN X uses 12 GB of GDDR5 across a 384-bit interface, yielding 336.6 GB/s of bandwidth. The RX 7900 GRE uses 16 GB of GDDR6 on a 256-bit bus, yet its higher 18 Gbps effective speed pushes bandwidth to 576.0 GB/s. The RX 7900 GRE also supports newer standards, including PCIe 4.0 x16 versus PCIe 3.0 x16, and offers DirectX 12 Ultimate (12_2) support compared to the TITAN X's DirectX 12 (12_1).

Head-to-Head Benchmarks

The head-to-head data consists of two compute-oriented tests, and the AMD Radeon RX 7900 GRE wins both decisively. In Geekbench OpenCL, the RX 7900 GRE scores 167913 against the TITAN X's 41155. This represents a 75.5% advantage, a massive leap that cannot be attributed to any single specification but rather the cumulative effect of more shading units, higher clocks, and newer memory technology.

The Geekbench Vulkan test shows a similar pattern. The RX 7900 GRE scores 144142, while the TITAN X manages 49038. The delta here is 66% in favor of AMD. Both results indicate that the RX 7900 GRE outperforms the TITAN X by a wide margin in raw compute throughput and API efficiency. The FP32 compute figures corroborate this: the RX 7900 GRE delivers 45.98 TFLOPS versus 6.691 TFLOPS for the TITAN X, a roughly 6.9x difference that dwarfs even the benchmark deltas.

Notably, the TITAN X does not win any of the two head-to-head tests, with winsA equal to 0 and winsB equal to 2. However, the aggregate average scores remain close because the TITAN X's benchmark suite includes Geekbench Metal (18723) and its OpenCL and Vulkan scores, while the RX 7900 GRE's average is pulled down by several low Passmark scores, including 139 in DirectX 10 and 107 in DirectX 12. This creates an interesting statistical situation where the two cards are near-parity in average score despite vastly different performance profiles.

Specification Differences

The specification sheets reveal differences in nearly every category. The TITAN X uses 28 nm process technology, while the RX 7900 GRE uses 5 nm. Transistor count jumps from 8,000 million to 57,700 million, with die size shrinking from 601 mm² to 529 mm². Clock speeds differ substantially: base clocks are 1000 MHz versus 1287 MHz, and boost clocks are 1089 MHz versus 2245 MHz. The RX 7900 GRE also lists a game clock of 1880 MHz, a field absent for the TITAN X.

Memory capacity increases from 12 GB GDDR5 to 16 GB GDDR6, and bandwidth rises from 336.6 GB/s to 576.0 GB/s, despite the bus width decreasing from 384-bit to 256-bit. Shading units increase from 3072 to 5120, TMUs from 192 to 320, and ROPs from 96 to 160. The RX 7900 GRE adds 80 ray tracing cores, which the TITAN X lacks. Pixel rate rises from 104.5 GPixel/s to 359.2 GPixel/s, and texture rate from 209.1 GTexel/s to 718.4 GTexel/s. FP32 performance increases from 6.691 TFLOPS to 45.98 TFLOPS, with the RX 7900 GRE also supporting FP16 at 91.96 TFLOPS.

Power and physical dimensions change as well. TDP rises slightly from 250 W to 260 W, with the power connector configuration changing from 1x 6-pin + 1x 8-pin to 2x 8-pin. The suggested PSU remains 600 W for both. The RX 7900 GRE is longer at 276 mm versus 267 mm, and wider at 51 mm versus 38 mm, though heights are similar at 110 mm and 111 mm. Display outputs differ, with the TITAN X offering 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2, while the RX 7900 GRE offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The bus interface moves from PCIe 3.0 x16 to PCIe 4.0 x16, and DirectX support advances from 12_1 to 12 Ultimate.

Where Each One Wins

Based strictly on the data, the AMD Radeon RX 7900 GRE wins in every head-to-head benchmark category. Its 75.5% lead in Geekbench OpenCL and 66% lead in Geekbench Vulkan make it the clear choice for compute-heavy workloads that leverage these APIs. The 16 GB memory capacity and 576.0 GB/s bandwidth provide a substantial advantage for large datasets and high-resolution textures. The presence of ray tracing cores gives it capabilities the TITAN X cannot match, and the FP16 support at 91.96 TFLOPS opens up workloads that are unavailable on the older card.

The NVIDIA GeForce GTX TITAN X's wins are more subtle and do not appear in the head-to-head tests. Its average benchmark score of 36305 is 0.6% higher than the RX 7900 GRE's 36101, suggesting that in the broader benchmark suite, it holds a slight edge in some legacy or specific tests. The TITAN X's 384-bit memory bus and dual-slot design with a shorter length of 267 mm may be preferable in certain system configurations. Its production status is end-of-life, but it remains a functional option for applications that rely on older driver ecosystems or specific Maxwell 2.0 optimizations.

The RX 7900 GRE's nearest rival data also shows it is competitive with other modern cards, sitting 0.7% above the AMD Radeon Pro Duo and 0.5% below the NVIDIA T1000. The TITAN X, meanwhile, sits 0.1% above the T1000 and 1.2% above the Radeon Pro Duo. These close margins in aggregate scoring mask the dramatic performance differences in individual compute tests, underscoring that the average score alone is an insufficient metric for comparing these two cards.

The Verdict

The data presents a clear recommendation for different use cases. The AMD Radeon RX 7900 GRE is the superior choice for any workload that leverages modern compute APIs, ray tracing, or high-bandwidth memory. Its 75.5% OpenCL advantage and 66% Vulkan advantage are decisive, and its 45.98 TFLOPS FP32 performance dwarfs the TITAN X's 6.691 TFLOPS. Gamers and professionals working with DirectX 12 Ultimate content, ray-traced scenes, or FP16 compute tasks should select the RX 7900 GRE without hesitation.

The NVIDIA GeForce GTX TITAN X, despite its end-of-life status, retains a marginal aggregate score advantage of 0.6% over the RX 7900 GRE. This comes from its performance in a different set of benchmarks, including Geekbench Metal where it scores 18723. For users constrained to older software ecosystems, Maxwell 2.0-specific optimizations, or systems that cannot accommodate the RX 7900 GRE's larger 51 mm width, the TITAN X remains a functional option. However, the data shows that in any direct compute comparison, the RX 7900 GRE wins outright. The verdict is unambiguous: the RX 7900 GRE is the more capable and future-proof GPU, while the TITAN X's only statistical edge is a negligible average score difference that does not translate to real-world compute wins.
