AMD Radeon RX 9070 vs NVIDIA GeForce GTX 1630 Comparison

The NVIDIA GeForce GTX 1630 and AMD Radeon RX 9070 occupy opposite ends of the hardware spectrum, separated not just by time but by fundamental design philosophy. The GTX 1630 is a low-profile Turing-era card aimed at basic 1080p output, while the RX 9070 is a current-generation RDNA 4.0 flagship targeting high-resolution, high-refresh gaming. The benchmark data reveals a predictable but stark performance chasm, yet the comparison also highlights how architectural evolution and market positioning create entirely different use cases for each product.

Where Each One Wins

The data presents a clear bifurcation in use cases. The AMD Radeon RX 9070 wins every head-to-head benchmark recorded, decisively taking both available tests. This makes it the obvious choice for any workload involving modern compute APIs, high-fidelity gaming, or content creation. Its Geekbench OpenCL score of 131,539 is over five times higher than the GTX 1630’s 24,858, indicating massive superiority in general-purpose GPU compute tasks like rendering, video encoding, and scientific simulations. The Vulkan score of 58,705 versus 23,695 reinforces this, showing the RX 9070 handles modern low-level graphics APIs with far greater efficiency.

Conversely, the NVIDIA GeForce GTX 1630 finds its niche not in raw performance but in legacy compatibility and physical footprint. With a 75 W TDP, single-slot design, and no power connectors, it is designed for office PCs, HTPCs, or older systems with weak power supplies. Its 4 GB of GDDR6 memory and 64-bit bus are sufficient for light gaming at lower resolutions, but its real strength lies in providing a stable display output for non-gaming tasks. The GTX 1630 also holds a slight edge in its nearest rival comparisons, sitting at the 70th percentile versus the RX 9070’s 69th percentile, though this is an artifact of averaging across all GPUs rather than a reflection of direct competition.

Architecture Differences

The architectural gulf between these two cards is immense. The GTX 1630 uses the TU117 chip on a 12 nm TSMC process, packing 4,700 million transistors into a 200 mm² die. This yields a transistor density of 23.5 million per mm². It is based on the Turing architecture, which lacks dedicated ray tracing cores or tensor cores, making it a pure rasterization engine. In contrast, the RX 9070 uses the Navi 48 chip on a current-generation 4 nm TSMC process, housing 53,900 million transistors in a 357 mm² die. This gives a transistor density of 151.0 million per mm², a six-fold increase in density that enables far more complex logic in a similar physical space.

The RDNA 4.0 architecture in the RX 9070 includes 56 dedicated ray tracing cores, a feature entirely absent from the GTX 1630. This allows hardware-accelerated ray tracing, which the older card cannot handle. The shading unit count tells the story: the RX 9070 has 3,584 shading units, 224 texture mapping units, and 128 ROPs, versus the GTX 1630’s 512, 32, and 16 respectively. This 7x difference in shader count directly translates to the compute throughput disparity. The RX 9070 also supports DirectX 12 Ultimate (12_2), while the GTX 1630 is limited to DirectX 12 (12_1), meaning the newer card can utilize features like mesh shaders and variable rate shading.

Head-to-Head Benchmarks

The two recorded head-to-head tests show a total rout for AMD. In Geekbench OpenCL, the RX 9070 scores 131,539 against the GTX 1630’s 24,858. This is a delta of -81.1% for NVIDIA, meaning the GTX 1630 achieves less than one-fifth the performance. OpenCL is a cross-platform compute standard, so this score reflects raw arithmetic throughput and memory bandwidth utilization. The RX 9070’s 36.13 TFLOPS FP32 performance and 644.6 GB/s bandwidth simply overwhelm the GTX 1630’s 1.828 TFLOPS and 96.00 GB/s.

The Geekbench Vulkan test narrows the gap slightly but remains lopsided. The RX 9070 scores 58,705 versus 23,695, a -59.6% delta. Vulkan is more sensitive to driver overhead and latency than pure compute, and the GTX 1630’s Turing architecture handles it reasonably well for its class. However, the RX 9070’s superior memory subsystem—256-bit bus versus 64-bit, 16 GB versus 4 GB—allows it to feed its shader array far more effectively. The delta percentage in Vulkan is smaller than OpenCL, suggesting the GTX 1630 is relatively less disadvantaged in gaming-like workloads than in pure compute, but it remains thoroughly outclassed.

FAQ

Q: Which card has better ray tracing performance?

A: The AMD Radeon RX 9070 has 56 dedicated ray tracing cores, while the NVIDIA GeForce GTX 1630 has none. The RX 9070 supports DirectX 12 Ultimate, which includes ray tracing features, whereas the GTX 1630 is limited to DirectX 12 (12_1) without hardware ray tracing support.

Q: How significant is the memory capacity difference?

A: The RX 9070 has 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s bandwidth. The GTX 1630 has 4 GB on a 64-bit bus, yielding only 96.00 GB/s. This roughly 6.7x bandwidth advantage allows the RX 9070 to handle high-resolution textures and large datasets without stuttering.

Q: Can the GTX 1630 run modern games at playable frame rates?

A: Benchmark results indicate the GTX 1630 performs at the 70th percentile among all GPUs, which is respectable for its class. However, its 4 GB memory and 1.828 TFLOPS FP32 performance limit it to older titles or low settings at 1080p. The RX 9070’s 36.13 TFLOPS and 16 GB memory make it suitable for current AAA games at high settings.

Q: What are the power requirements for each card?

A: The GTX 1630 has a 75 W TDP, requires no power connectors, and a suggested 250 W PSU. The RX 9070 has a 220 W TDP, needs two 8-pin connectors, and a suggested 550 W PSU. This makes the GTX 1630 suitable for pre-built systems with minimal power headroom.

Q: Which card has better Vulkan performance?

A: The RX 9070 wins with a score of 58,705 versus 23,695 for the GTX 1630, a -59.6% delta. While the GTX 1630 is less disadvantaged in Vulkan than OpenCL, the RX 9070’s superior hardware still dominates.

Q: How do these cards compare to their nearest rivals?

A: The GTX 1630’s average benchmark score of 24,277 places it 0.2% ahead of the GTX 780 Ti and 0.4% ahead of the RTX 2080 SUPER. The RX 9070’s average of 23,877 is 0.6% above the GTX TITAN Z but 0.8% below the RX 6800S. Both cards sit near the performance of much older or differently positioned products.

The Verdict

The data leaves no ambiguity for performance-seeking users: the AMD Radeon RX 9070 is the only choice for modern gaming or compute workloads. Its 131,539 OpenCL and 58,705 Vulkan scores dwarf the GTX 1630, and its 56 ray tracing cores plus 16 GB memory make it future-proof for years. The 4 nm process enables 36.13 TFLOPS FP32, a 19.8x improvement over the GTX 1630, which is an insurmountable gap in any real-world scenario.

The NVIDIA GeForce GTX 1630 serves a narrow but valid purpose. Its 75 W power draw, single-slot design, and lack of external power connectors mean it can drop into legacy systems without upgrades. For users running office productivity, media playback, or very old games, its 4 GB memory and 1.828 TFLOPS are adequate. Its 70th percentile ranking versus the RX 9070’s 69th is misleading—this reflects the GTX 1630’s strong standing among low-end cards, not competitiveness with the RDNA 4.0 flagship.

The verdict is straightforward: buy the RX 9070 if you need performance and have a 550 W PSU. Choose the GTX 1630 if you must work within tight power and space constraints and have no compute or gaming ambitions beyond the basics. There is no middle ground in this comparison—the architectural and generational divide is too wide.
