AMD Radeon RX 6700M vs NVIDIA GeForce GTX TITAN Z Comparison

The AMD Radeon RX 6700M is decisively faster than the NVIDIA GeForce GTX TITAN Z in every benchmark comparison available, with the data showing a generational leap in compute performance that dwarfs the older card’s specifications. In the two direct head-to-head tests, the RX 6700M wins both, delivering a 205% higher score in Geekbench OpenCL and a 312.7% higher score in Geekbench Vulkan, making the GTX TITAN Z appear as a legacy product rather than a direct competitor.

Head-to-Head Benchmarks

The most striking result comes from the Geekbench Vulkan test, where the AMD Radeon RX 6700M scores 90,816 points against the NVIDIA GeForce GTX TITAN Z’s 22,006 points. That is a delta of 312.7% in favor of the RX 6700M, meaning the newer card delivers more than four times the Vulkan compute performance. This is not a marginal improvement; it is a complete overhaul of the underlying architecture. The RX 6700M’s RDNA 2.0 design with 36 dedicated ray tracing cores and support for Vulkan 1.4 simply outclasses the GTX TITAN Z’s Kepler architecture, which only offers Vulkan 1.2.175 support and has no ray tracing hardware at all.

In the Geekbench OpenCL test, the RX 6700M again dominates, scoring 77,666 points versus the GTX TITAN Z’s 25,465 points, a 205% advantage. This result aligns with the raw compute specifications: the RX 6700M delivers 11.06 TFLOPS of FP32 performance, while the GTX TITAN Z manages only 5.046 TFLOPS. The RX 6700M also has a significant edge in memory bandwidth efficiency, despite having a narrower 160-bit bus compared to the GTX TITAN Z’s 384-bit bus. The RX 6700M’s GDDR6 memory at 16 Gbps effective achieves 320.0 GB/s, while the GTX TITAN Z’s GDDR5 at 7 Gbps effective reaches 336.0 GB/s—a mere 5% difference in bandwidth, yet the RX 6700M still wins by triple-digit percentages.

The overall benchmark averages reinforce this narrative. The RX 6700M holds an average benchmark score of 25,633 across all tests, placing it at the 71st percentile of all GPUs. The GTX TITAN Z averages 23,736, ranking at the 69th percentile. While the percentile gap appears small—just 2 points—the head-to-head deltas reveal the true performance chasm. The RX 6700M’s nearest rivals include the NVIDIA GeForce RTX 3080 Ti Mobile (average score 25,740, delta -0.4%) and the AMD Radeon Pro W5700 (average score 25,726, delta -0.4%), showing it trades blows with modern high-end mobile parts. The GTX TITAN Z’s nearest rivals are the NVIDIA GeForce RTX 3080 Mobile (average score 23,628, delta 0.5%) and the AMD Radeon RX 9070 (average score 23,877, delta -0.6%), placing it in the same performance tier as current mid-range offerings.

Where Each One Wins

The AMD Radeon RX 6700M wins in every measurable category from the data. In compute-intensive workloads, it is untouchable. The Geekbench OpenCL and Vulkan results show that the RX 6700M is not just faster but categorically superior, with deltas of 205% and 312.7% respectively. This makes it the clear choice for GPU-accelerated tasks such as rendering, scientific simulation, or any workload that leverages OpenCL or Vulkan compute.

For the NVIDIA GeForce GTX TITAN Z, there are no benchmark wins in the data. However, the specification sheet reveals where it has theoretical advantages that do not translate into real-world performance. The GTX TITAN Z has 2,880 shading units versus the RX 6700M’s 2,304, and 240 texture mapping units versus 144, yet it still loses decisively. The GTX TITAN Z does have a wider 384-bit memory bus and slightly higher raw bandwidth at 336.0 GB/s, but the RX 6700M’s newer memory technology and higher clocks—2,400 MHz boost versus 876 MHz boost—overcome that deficit. The GTX TITAN Z also has a higher transistor density per square millimeter in absolute terms, but that is due to its larger die size (561 mm² versus 335 mm²) rather than architectural efficiency.

The RX 6700M also wins on efficiency and practical deployment. Its 135 W TDP is less than half of the GTX TITAN Z’s 375 W, and it requires no external power connectors, running as an integrated graphics processor (IGP) solution. The GTX TITAN Z demands a 750 W recommended power supply and uses 2x 8-pin connectors, making it a power-hungry desktop behemoth. The RX 6700M’s PCIe 4.0 x16 interface also doubles the bandwidth of the GTX TITAN Z’s PCIe 3.0 x16, which matters for data transfer in compute tasks.

The Verdict

The data is unambiguous: the AMD Radeon RX 6700M is the superior product for virtually any use case. If you need a GPU for modern compute workloads, the RX 6700M delivers 205% higher OpenCL performance and 312.7% higher Vulkan performance, making it a no-brainer choice. Its 71st percentile ranking among all GPUs, alongside rivals like the RTX 3080 Ti Mobile, places it in a performance class that the GTX TITAN Z cannot approach. The GTX TITAN Z’s 69th percentile ranking, with rivals like the RTX 3080 Mobile and RX 9070, shows it is merely a mid-range performer today, despite its 2014 flagship status.

For users who prioritize raw compute power and modern API support, the RX 6700M wins outright. It offers 10 GB of GDDR6 memory versus the GTX TITAN Z’s 6 GB of GDDR5, a 7 nm process versus 28 nm, and ray tracing capability that the GTX TITAN Z lacks entirely. The RX 6700M also supports DirectX 12 Ultimate (12_2) compared to the GTX TITAN Z’s DirectX 12 (11_1), which is a critical distinction for gaming and future-proofing.

The only scenario where the GTX TITAN Z might be preferred is if you require its specific display outputs—2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2—for legacy hardware compatibility, or if you need a triple-slot desktop card with a 267 mm length. But from a performance standpoint, the data shows no reason to choose it. The GTX TITAN Z’s launch MSRP was 2,999 USD, which is a historical fact, but its performance today does not justify that legacy price point in any benchmark metric.

Architecture Differences

The two GPUs represent completely different eras of design. The AMD Radeon RX 6700M uses the Navi 22 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. This allows for 17,200 million transistors packed into a 335 mm² die, achieving a transistor density of 51.3 million per square millimeter. The architecture includes 36 ray tracing cores, enabling hardware-accelerated ray tracing for supported games and applications. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6, making it fully modern in API support.

In contrast, the NVIDIA GeForce GTX TITAN Z uses the GK110B chip based on the Kepler architecture, built on a 28 nm process at TSMC. It contains 7,080 million transistors on a larger 561 mm² die, with a transistor density of just 12.6 million per square millimeter. Kepler lacks ray tracing and tensor cores entirely, and its API support is limited to DirectX 12 (11_1), Vulkan 1.2.175, and OpenGL 4.6. The GTX TITAN Z’s memory subsystem uses GDDR5 at 7 Gbps effective, while the RX 6700M uses GDDR6 at 16 Gbps effective, doubling the effective memory speed.

The RX 6700M’s RDNA 2.0 architecture also introduces a 2:1 FP16 ratio, delivering 22.12 TFLOPS of half-precision performance, whereas the GTX TITAN Z has no FP16 data available. This makes the RX 6700M more suitable for AI and machine learning workloads that rely on reduced precision. The RX 6700M also supports PCIe 4.0 x16, doubling the bandwidth of the GTX TITAN Z’s PCIe 3.0 x16 interface, which is crucial for data-heavy compute tasks.

Specification Differences

The most significant specification differences between the two GPUs are stark. The RX 6700M has 10 GB of GDDR6 memory on a 160-bit bus, while the GTX TITAN Z has 6 GB of GDDR5 on a 384-bit bus. Despite the narrower bus, the RX 6700M achieves 320.0 GB/s bandwidth due to faster memory clocks, versus the GTX TITAN Z’s 336.0 GB/s.

In terms of processing units, the RX 6700M has 2,304 shading units, 144 TMUs, and 64 ROPs, while the GTX TITAN Z has 2,880 shading units, 240 TMUs, and 48 ROPs. The RX 6700M’s higher ROP count aids pixel throughput, giving it 153.6 GPixel/s versus the GTX TITAN Z’s 52.56 GPixel/s. Texture rate also favors the RX 6700M at 345.6 GTexel/s versus 210.2 GTexel/s.

Clock speeds are dramatically different: the RX 6700M runs at a base of 1489 MHz and boosts to 2400 MHz, while the GTX TITAN Z runs at 705 MHz base and 876 MHz boost. The RX 6700M also has a game clock of 2300 MHz, which the GTX TITAN Z lacks. Power consumption reflects the generational gap: the RX 6700M’s TDP is 135 W, while the GTX TITAN Z draws 375 W. The RX 6700M is an IGP with no power connectors, whereas the GTX TITAN Z is a triple-slot card requiring 2x 8-pin connectors and a 750 W PSU. Finally, the RX 6700M uses PCIe 4.0 x16, while the GTX TITAN Z uses PCIe 3.0 x16.
