AMD Radeon R9 M395X vs NVIDIA GeForce RTX 3070 Ti Comparison

Head-to-Head Benchmarks

The recorded data contains exactly one direct head-to-head benchmark between the NVIDIA GeForce RTX 3070 Ti and the AMD Radeon R9 M395X: the Geekbench OpenCL test. The results are dramatic. The RTX 3070 Ti scores 119,718 points, while the R9 M395X manages 17,829 points. That translates to a 571.5% advantage for the NVIDIA card. In other words, the RTX 3070 Ti is roughly 6.7 times faster in this compute workload. This is not a close contest by any metric.

Looking at the broader picture, the RTX 3070 Ti's average benchmark score across all recorded tests is 29,945. The R9 M395X's average is 25,891. That difference, about 15.7% in favor of the newer card, seems modest until you consider the context. The RTX 3070 Ti sits at the 75th percentile among all GPUs in the database, while the R9 M395X sits at the 71st. Both are respectable positions, but the gap in raw compute performance is enormous.

The R9 M395X does have one benchmark result that is not shared with the RTX 3070 Ti: a Geekbench Metal score of 33,953. However, since the NVIDIA card does not have a Metal result recorded, this cannot be compared directly. The only overlapping test is OpenCL, and there the older AMD card is decisively outpaced.

Where Each One Wins

Based on the available data, the NVIDIA GeForce RTX 3070 Ti wins in every category where both cards have measurements. The OpenCL result is the sole common benchmark, and it is a landslide. The RTX 3070 Ti's other recorded scores, such as 23,356 in Passmark G3D and 11,601 in Passmark GPU Compute, further illustrate its strength in general graphics and compute tasks. Its 3DMark Steel Nomad DX12 score of 3,478 and Geekbench Vulkan score of 139,541 reinforce a pattern of modern API proficiency.

The AMD Radeon R9 M395X, by contrast, has only two recorded benchmarks: the Metal score of 33,953 and the OpenCL score of 17,829. The Metal score suggests it can handle Apple-centric graphics workloads, but without a comparable NVIDIA Metal result, the significance is limited. In the one test where both cards appear, the R9 M395X is 571.5% behind. The data does not support any use case where the older card wins outright.

For pure compute tasks, such as OpenCL workloads, the RTX 3070 Ti is the clear choice. For modern gaming and DirectX 12 titles, the RTX 3070 Ti's Passmark DirectX 12 score of 91 versus the R9 M395X's lack of any DirectX 12 result in the database suggests the newer card is better equipped. The R9 M395X's relevance appears confined to legacy systems or platforms where its specific feature set, such as Metal support, is required.

Architecture Differences

The architectural gap between these two GPUs is generational. The NVIDIA GeForce RTX 3070 Ti uses the GA104 chip built on Ampere architecture, manufactured on an 8 nm process at Samsung. It packs 17,400 million transistors onto a 392 mm² die, yielding a transistor density of 44.4M per mm². The AMD Radeon R9 M395X uses the Amethyst chip based on GCN 3.0 architecture, built on a 28 nm process at TSMC. That chip contains 5,000 million transistors on a 366 mm² die, for a density of just 13.7M per mm².

The differences in core configuration are stark. The RTX 3070 Ti has 6,144 shading units, 192 texture mapping units, and 96 raster output units. The R9 M395X has 2,048 shading units, 128 TMUs, and 32 ROPs. The NVIDIA card also includes 48 RT cores and 192 tensor cores, features entirely absent from the older AMD chip. These specialized cores enable hardware-accelerated ray tracing and AI-driven features like DLSS, which the R9 M395X cannot offer.

Memory technology also separates the two. The RTX 3070 Ti uses 8 GB of GDDR6X on a 256-bit bus, delivering 608.3 GB/s of bandwidth. The R9 M395X also has 8 GB, but it is GDDR5 on the same 256-bit bus, yielding only 160.0 GB/s. That is a 3.8 times bandwidth advantage for the newer card. Clock speeds follow the same pattern: the RTX 3070 Ti runs at 1575 MHz base and 1770 MHz boost, while the R9 M395X has no recorded base or boost clocks, only a memory clock of 1250 MHz (5 Gbps effective).

The feature set diverges further. The RTX 3070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The R9 M395X supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA card uses PCIe 4.0 x16, while the AMD card uses PCIe 3.0 x16. Power requirements also differ: the RTX 3070 Ti has a 290 W TDP with a 1x 12-pin connector and a suggested 600 W PSU, whereas the R9 M395X has a 75 W TDP with no power connectors and no suggested PSU listed. The R9 M395X is an MXM module, meaning it is designed for laptops or proprietary systems, while the RTX 3070 Ti is a dual-slot desktop card measuring 267 mm in length.

The Verdict

The data points overwhelmingly toward the NVIDIA GeForce RTX 3070 Ti as the superior performer. Its 571.5% lead in OpenCL, combined with a 75th versus 71st percentile standing, leaves little room for ambiguity. The RTX 3070 Ti is also far more feature-rich: it has 3 times the shading units, 3 times the ROPs, 48 RT cores, 192 tensor cores, and nearly 4 times the memory bandwidth. It supports newer API versions and a faster PCIe interface.

The AMD Radeon R9 M395X, however, is not without its niche. Its 75 W TDP and MXM form factor make it suitable for portable or proprietary systems where power and space are constrained. Its Metal benchmark score of 33,953 indicates some capability in Apple-oriented workflows. But even there, the lack of comparative data prevents a definitive conclusion.

For anyone building or upgrading a desktop system with modern gaming or compute needs, the RTX 3070 Ti is the obvious choice. It delivers roughly 7.3 times the FP32 throughput (21.75 TFLOPS versus 2.961 TFLOPS) and 7.3 times the texture rate (339.8 GTexel/s versus 92.54 GTexel/s). The R9 M395X, by contrast, is best suited for legacy systems or scenarios where its low power draw and modular design are the primary requirements. The database records make the verdict clear: the RTX 3070 Ti wins on every measurable front where both cards can be compared.
