AMD Radeon R9 M290X vs AMD Radeon RX 9070 Comparison

The AMD Radeon RX 9070 and the AMD Radeon R9 M290X represent two entirely different eras of graphics technology, separated by over a decade of architectural evolution. The data presents a stark generational divide: the RX 9070, built on the 4 nm process with RDNA 4.0, utterly eclipses the older GCN 1.0-based R9 M290X in every measurable category. The sole head-to-head benchmark shows the RX 9070 delivering a 497.1% higher score in Geekbench OpenCL, a margin that underscores the enormous performance gulf. While both cards occupy similar percentile rankings among all GPUs (69th for the RX 9070 vs. 68th for the R9 M290X), this is a statistical artifact of the database's broader distribution; in direct comparison, the RX 9070 is in a completely different performance class. The R9 M290X, an end-of-life mobile module from 2014, is not a competitor but a historical artifact, while the RX 9070 is an active, current-generation desktop part.

The Verdict

The data is unambiguous: the AMD Radeon RX 9070 is the definitive choice for any modern workload. Its average benchmark score of 23,877 is only 0.6% higher than the NVIDIA GeForce GTX TITAN Z and 1.1% higher than the NVIDIA GeForce RTX 3080 Mobile, placing it firmly in the upper echelon of current graphics hardware. Its 69th percentile ranking among all GPUs confirms it as a high-performing part. For gaming, content creation, or any GPU-accelerated task, the RX 9070 is the only rational option, delivering over 16 GB of GDDR6 memory, 36.13 TFLOPS of FP32 compute, and full DirectX 12 Ultimate support.

Conversely, the AMD Radeon R9 M290X is a legacy product. With an average benchmark score of 23,276, it sits statistically near the RX 9070's rivals, including the AMD Radeon RX 6600M (0% delta) and the NVIDIA P106-100 (0.1% delta). However, its 68th percentile ranking is misleading in this context. The R9 M290X’s 4 GB of GDDR5 memory, 2.304 TFLOPS of FP32 compute, and GCN 1.0 architecture from 2014 place it far behind modern standards. It is not suitable for current AAA titles or demanding applications. The verdict is simple: the RX 9070 is for anyone building or upgrading a desktop PC today; the R9 M290X is only relevant for historical reference or proprietary, legacy mobile systems.

Where Each One Wins

The AMD Radeon RX 9070 wins in every scenario that matters for a contemporary user. Its 16 GB frame buffer is essential for high-resolution textures and modern game assets, while its 644.6 GB/s of memory bandwidth provides the data throughput required for 4K gaming and complex compute tasks. The card’s 2520 MHz boost clock and 36.13 TFLOPS FP32 performance make it a clear winner for ray tracing, AI-accelerated workloads, and high-refresh-rate gaming. Its support for PCIe 5.0 x16 and DisplayPort 2.1a ensures compatibility with the latest platforms and displays.

The AMD Radeon R9 M290X has no competitive wins in the data. Its only benchmarks, Geekbench Metal (24,524) and Geekbench OpenCL (22,028), are far below the RX 9070's scores. Its 100 W TDP and MXM module form factor indicate its purpose was for high-end laptops of its era, not for modern performance. The R9 M290X’s only nominal advantage is its lower power draw and lack of external power connectors, but this is irrelevant for a desktop comparison. In terms of raw performance, features, and capability, the RX 9070 is the sole winner across every category.

Architecture Differences

The architectural gap between these two GPUs is vast and explains the performance disparity. The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. This allows for a massive 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0M / mm². It features 3,584 shading units, 224 texture mapping units, and 128 ROPs, alongside 56 dedicated ray tracing cores. Its memory subsystem consists of 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The card operates with a base clock of 1330 MHz, a boost clock of 2520 MHz, and a game clock of 2070 MHz. It supports the latest APIs, including DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6.

In contrast, the AMD Radeon R9 M290X uses the ancient GCN 1.0 architecture, built on a 28 nm process, also at TSMC. This older node limits it to 2,800 million transistors on a 212 mm² die, with a much lower transistor density of 13.2M / mm². It has 1,280 shading units, 80 TMUs, and 32 ROPs, with no dedicated ray tracing hardware. Its memory is 4 GB of GDDR5 on a 256-bit bus, providing 153.6 GB/s of bandwidth—a fraction of the RX 9070's. The R9 M290X's clocks are also far lower, with a base of 850 MHz and a boost of 900 MHz. It supports DirectX 12 (11_1), Vulkan 1.2.170, and OpenGL 4.6. The difference in transistor count alone (53,900 million vs. 2,800 million) highlights the immense complexity and capability of the newer chip. The RX 9070's 56 RT cores are entirely absent on the R9 M290X, explaining the lack of modern ray tracing features.

Head-to-Head Benchmarks

The head-to-head benchmark data provides a single, decisive data point: the Geekbench OpenCL test. In this compute-heavy workload, the AMD Radeon RX 9070 scores 131,539, while the AMD Radeon R9 M290X scores 22,028. This results in a 497.1% delta in favor of the RX 9070, marking a landslide victory. This test measures general-purpose compute performance across a wide range of tasks, and the result reflects the enormous advantage the RX 9070 holds in raw throughput.

The only other benchmark available for the R9 M290X is Geekbench Metal, where it scores 24,524. The RX 9070 does not have a Metal score listed, as it is a DirectX/Vulkan-oriented part for Windows and Linux. However, this score is still far lower than the RX 9070's OpenCL score, indicating a general compute performance gap that is insurmountable for the older card. The RX 9070 also has a Vulkan score of 58,705, which is more than double the R9 M290X's total compute output. In every available metric, the RX 9070 is the clear and overwhelming winner. Its 36.13 TFLOPS FP32 compute dwarfs the R9 M290X's 2.304 TFLOPS, and its 564.5 GTexel/s texture rate and 322.6 GPixel/s pixel rate are similarly dominant. The R9 M290X, with its 72.00 GTexel/s and 28.80 GPixel/s rates, cannot compete on any level.
