AMD Radeon RX 7900 XT vs NVIDIA GeForce GTX TITAN Comparison

# NVIDIA GeForce GTX TITAN vs AMD Radeon RX 7900 XT

The head-to-head data splits exactly one win apiece: the GTX TITAN dominates Geekbench OpenCL by 95%, while the RX 7900 XT crushes the TITAN in Geekbench Vulkan by 85.9%. The verdict is not about overall speed — it is about era and API. The RX 7900 XT is the modern choice for any Vulkan-based workload, and the GTX TITAN is a legacy OpenCL specialist that holds a surprising edge in that single test. Neither card is a general-purpose winner across the board; the data shows two very different products optimized for different software environments.

The Verdict

From the benchmark results, the AMD Radeon RX 7900 XT is the card to choose for anyone running Vulkan applications. Its Geekbench Vulkan score of 71,068 is nearly 7.1 times higher than the GTX TITAN’s 10,027, a delta of 85.9% in AMD’s favor. That is not a marginal improvement; it is a generational leap in API efficiency. The RX 7900 XT also delivers 51.48 TFLOPS FP32, 459.6 GPixel/s pixel rate, and 804.4 GTexel/s texture rate — all figures that dwarf the TITAN’s 4.709 TFLOPS, 49.06 GPixel/s, and 196.2 GTexel/s. For any modern gaming or compute load that uses Vulkan or DirectX 12 Ultimate, the RX 7900 XT is the definitive pick.

However, the NVIDIA GeForce GTX TITAN wins the only OpenCL comparison in the data. Its Geekbench OpenCL score of 24,873 beats the RX 7900 XT’s 12,756 by 95%. This is a remarkable result for a 2013 card, and it means that for legacy OpenCL workloads — particularly those that were written for Kepler-era compute — the TITAN remains not just viable but superior. The TITAN also carries a higher average benchmark score of 14,373 versus the RX 7900 XT’s 13,745, and it ranks at the 56th percentile of all GPUs, one point above the RX 7900 XT’s 55th percentile.

The production status for both cards is end-of-life, so this is not a purchase recommendation for new builds. But if you are choosing between them from existing inventory or a used market, the decision hinges entirely on your software stack. Vulkan and DirectX 12 users go AMD. OpenCL users go NVIDIA. There is no middle ground in the data.

Architecture Differences

The two cards are separated by nearly a decade of semiconductor evolution. The GTX TITAN uses the GK110 chip on NVIDIA’s Kepler architecture, built on a 28 nm process at TSMC, with 7,080 million transistors on a 561 mm² die. The RX 7900 XT uses the Navi 31 chip on AMD’s RDNA 3.0 architecture, built on a 5 nm process at TSMC, with 57,700 million transistors on a 529 mm² die. The transistor density tells the story: the RX 7900 XT packs 109.1M transistors per mm², versus the TITAN’s 12.6M per mm² — an 8.7 times density increase.

The memory subsystems are completely different generations. The TITAN has 6 GB of GDDR5 on a 384-bit bus, delivering 288.4 GB/s of bandwidth. The RX 7900 XT has 20 GB of GDDR6 on a 320-bit bus, delivering 800.0 GB/s. Note that the RX 7900 XT achieves more than 2.7 times the bandwidth despite a narrower bus, thanks to the faster GDDR6 memory clocked at 20 Gbps effective versus the TITAN’s 6 Gbps effective.

Compute resources also differ massively. The TITAN has 2,688 shading units, 224 texture mapping units, and 48 raster output pipelines. The RX 7900 XT has 5,376 shading units, 336 TMUs, and 192 ROPs — which explains its 9.4 times higher pixel rate and 4.1 times higher texture rate. The RX 7900 XT also has 84 dedicated ray tracing cores, a feature the TITAN lacks entirely. The TITAN supports DirectX 12 (11_0) while the RX 7900 XT supports DirectX 12 Ultimate (12_2), and the Vulkan API support differs from 1.2.175 on the TITAN to 1.4 on the RX 7900 XT.

Specification Differences

The two cards differ in nearly every measurable specification. The process node shifts from 28 nm on the TITAN to 5 nm on the RX 7900 XT. Transistor count jumps from 7,080 million to 57,700 million, while die size shrinks slightly from 561 mm² to 529 mm². Transistor density increases from 12.6M per mm² to 109.1M per mm².

Clock speeds are radically different. The TITAN runs at 836 MHz base and 876 MHz boost, while the RX 7900 XT runs at 1,387 MHz base, 2,025 MHz game clock, and 2,394 MHz boost. Memory clocks go from 1,502 MHz (6 Gbps effective) on the TITAN to 2,500 MHz (20 Gbps effective) on the RX 7900 XT.

Compute resources differ: shading units go from 2,688 to 5,376, TMUs from 224 to 336, and ROPs from 48 to 192. The RX 7900 XT adds 84 RT cores. Pixel rate improves from 49.06 GPixel/s to 459.6 GPixel/s, texture rate from 196.2 GTexel/s to 804.4 GTexel/s, and FP32 from 4.709 TFLOPS to 51.48 TFLOPS. The RX 7900 XT also has FP16 performance of 103.0 TFLOPS (2:1), which the TITAN does not list.

Power and connectivity also diverge. The TITAN draws 250 W TDP with a 600 W suggested PSU, while the RX 7900 XT draws 300 W TDP with a 700 W suggested PSU. Power connectors go from 1x 6-pin + 1x 8-pin to 2x 8-pin. The bus interface upgrades from PCIe 3.0 x16 to PCIe 4.0 x16. Display outputs change from 2x DVI, 1x HDMI 1.4a, 1x DisplayPort 1.2 to 1x HDMI 2.1a, 2x DisplayPort 2.1, 1x USB Type-C. The TITAN measures 267 mm long, 111 mm high, and 38 mm wide, while the RX 7900 XT is 276 mm long, 110 mm high, and 51 mm wide — both dual-slot cards.

Head-to-Head Benchmarks

The head-to-head data contains exactly two benchmarks, and each card wins one. The GTX TITAN’s Geekbench OpenCL score of 24,873 versus the RX 7900 XT’s 12,756 is a 95% delta — the TITAN nearly doubles the AMD card’s score. This is the single largest margin in either direction across the entire comparison. For OpenCL compute, the Kepler architecture’s 2,688 shading units at a modest 836 MHz base clock apparently deliver better performance than the RDNA 3.0 card’s 5,376 shading units, at least in this specific test.

The RX 7900 XT responds in Geekbench Vulkan with a score of 71,068 versus the TITAN’s 10,027, an 85.9% delta in AMD’s favor. The Vulkan score difference is staggering: the RX 7900 XT achieves roughly 7.1 times the TITAN’s score. This reflects not just the hardware improvements but also the API maturity — the TITAN supports Vulkan 1.2.175, while the RX 7900 XT supports Vulkan 1.4, and the underlying driver and hardware have evolved to exploit Vulkan far more effectively.

The wins are evenly split at 1-1, but the magnitude matters. The TITAN’s OpenCL win is a 95% margin, while the RX 7900 XT’s Vulkan win is an 85.9% margin. Both are decisive, but they measure different things. OpenCL is a general-purpose compute API, while Vulkan is primarily a graphics and low-level compute API. The data suggests that if your workload is OpenCL-based, the TITAN is not just competitive — it is dominant. If your workload is Vulkan-based, the RX 7900 XT is in a different league entirely.

Where Each One Wins

The GTX TITAN wins in OpenCL compute. Its Geekbench OpenCL score of 24,873 is 95% higher than the RX 7900 XT’s 12,756, making it the clear choice for any application that relies on OpenCL for general-purpose GPU compute. This includes legacy scientific computing, older rendering pipelines, and certain professional workloads that were optimized for Kepler-era hardware. The TITAN also edges out the RX 7900 XT on average benchmark score (14,373 vs 13,745) and percentile rank (56th vs 55th), though these differences are small — 4.6% and one percentile point, respectively.

The RX 7900 XT wins in Vulkan and modern graphics. Its Geekbench Vulkan score of 71,068 versus the TITAN’s 10,027 is an 85.9% delta, and this is where the card’s architectural advantages become clear. The RX 7900 XT has 84 RT cores, 20 GB of GDDR6 memory, and 800.0 GB/s of bandwidth, making it suitable for ray-traced games, DirectX 12 Ultimate titles, and Vulkan-based applications. The 51.48 TFLOPS FP32 and 459.6 GPixel/s pixel rate ensure that modern graphics workloads are handled with headroom to spare. For any use case involving current game engines or Vulkan-based compute, the RX 7900 XT is the only rational choice.

The production status for both cards is end-of-life, so neither is a future-proof investment. But within the data presented, the use-case split is clean: OpenCL legacy compute belongs to the GTX TITAN, and everything modern belongs to the RX 7900 XT. The RX 7900 XT also carries a lower launch MSRP of 899 USD versus the TITAN’s 999 USD, though both are historical figures given their end-of-life status. The choice, if you must make one, is entirely determined by your software environment.
