AMD Radeon RX 7700 XT vs NVIDIA GeForce GTX 1630 Comparison

The GeForce GTX 1630 and the Radeon RX 7700 XT occupy vastly different tiers of the graphics card market, a fact immediately evident from their benchmark scores and specifications. The GTX 1630 is an end-of-life, entry-level Turing part designed for basic 1080p output, while the RX 7700 XT is an active, high-performance RDNA 3.0 card aimed at demanding gaming and compute workloads. The data shows a clear chasm in raw performance, architectural capability, and memory resources, making the choice between them dependent entirely on the user's performance requirements and budget constraints.

Where Each One Wins

The benchmark results offer a stark contrast in performance domains. The AMD Radeon RX 7700 XT is the definitive winner in every measured category, with its advantages ranging from substantial to overwhelming. Its most dominant victory comes in the Geekbench OpenCL test, where it scores 138,383 points compared to the GTX 1630's 24,858 points, representing a 82% delta in favor of AMD. This massive lead indicates that the RX 7700 XT is in a completely different performance class, suited for compute-heavy applications, modern gaming at high resolutions, and any workload that can leverage its immense parallel processing power.

The NVIDIA GeForce GTX 1630, conversely, finds its niche not in winning benchmarks against the RX 7700 XT, but in its fundamental design philosophy. With a 75 W TDP, single-slot form factor, and no power connectors required, it is a card designed for maximum compatibility and minimal power draw. Its 4 GB of GDDR6 memory and 64-bit bus are adequate for light, esports-style gaming or as a display output solution for basic office or media PCs. While it loses every head-to-head comparison, its value proposition lies in its simplicity and low power envelope, making it the only sensible choice for systems with very limited power supplies or where a dual-slot, 245 W card like the RX 7700 XT physically cannot fit.

FAQ

Q: Which card has a higher average benchmark score?

A: The NVIDIA GeForce GTX 1630 has a higher average benchmark score of 24,277, compared to the AMD Radeon RX 7700 XT's 22,549. However, this is because the GTX 1630's average is based on only two Geekbench tests, while the RX 7700 XT's average includes a broader range of tests, including several Passmark tests where it scores lower.

Q: What are the core clock speeds of the two cards?

A: The NVIDIA GeForce GTX 1630 has a base clock of 1740 MHz and a boost clock of 1785 MHz. The AMD Radeon RX 7700 XT has a lower base clock of 1435 MHz but a significantly higher boost clock of 2544 MHz, with a game clock of 2171 MHz.

Q: How much memory does each card have?

A: The NVIDIA GeForce GTX 1630 is equipped with 4 GB of GDDR6 memory on a 64-bit bus, providing 96.00 GB/s of bandwidth. The AMD Radeon RX 7700 XT features 12 GB of GDDR6 memory on a 192-bit bus, offering 432.0 GB/s of bandwidth.

Q: Which card supports hardware ray tracing?

A: The AMD Radeon RX 7700 XT supports hardware ray tracing, as it includes 54 ray tracing cores. The NVIDIA GeForce GTX 1630 does not have ray tracing cores, as its Turing architecture implementation lacks this feature.

Q: What is the power consumption difference?

A: The NVIDIA GeForce GTX 1630 has a TDP of 75 W and requires no power connectors, with a suggested PSU of 250 W. The AMD Radeon RX 7700 XT has a TDP of 245 W, requires two 8-pin power connectors, and needs a 550 W suggested PSU.

Q: Are both cards compatible with the latest PCIe standard?

A: No. The AMD Radeon RX 7700 XT uses a PCIe 4.0 x16 interface, while the NVIDIA GeForce GTX 1630 uses the older PCIe 3.0 x16 interface.

Head-to-Head Benchmarks

The head-to-head data provides only two direct comparison points, both of which are decisively won by the AMD Radeon RX 7700 XT. The most significant disparity is in the Geekbench OpenCL test. Here, the RX 7700 XT scores 138,383, while the GTX 1630 manages just 24,858. This yields a delta of -82% from the perspective of the NVIDIA card, indicating that the AMD card is over five times faster in this compute-oriented benchmark. This test is particularly relevant for professional applications, video encoding, and physics simulations, where the RX 7700 XT's 35.17 TFLOPS of FP32 performance and 3456 shading units provide an insurmountable advantage over the GTX 1630's 1.828 TFLOPS and 512 shading units.

The second benchmark, Geekbench Vulkan, shows a closer but still lopsided result. The RX 7700 XT scores 46,443, compared to the GTX 1630's 23,695, resulting in a 49% delta. While the Vulkan API is a low-overhead graphics interface that can benefit both cards, the RX 7700 XT's superior memory bandwidth (432.0 GB/s vs 96.00 GB/s) and higher pixel rate (244.2 GPixel/s vs 28.56 GPixel/s) allow it to excel in modern, draw-call-heavy game engines. The GTX 1630's performance is sufficient for older titles or very low graphical settings, but the data confirms it cannot compete in any scenario that stresses the GPU's geometry or fill-rate capabilities.

Specification Differences

The two cards diverge on nearly every core specification, reflecting their different market positions. The most fundamental difference is in memory configuration: the GTX 1630 offers 4 GB of GDDR6 on a 64-bit bus, while the RX 7700 XT provides 12 GB on a 192-bit bus. This leads to a bandwidth disparity of 96.00 GB/s versus 432.0 GB/s, which is critical for high-resolution textures and compute workloads. The processing power is equally disparate, with the GTX 1630 featuring 512 shading units, 32 TMUs, and 16 ROPs, whereas the RX 7700 XT boasts 3456 shading units, 216 TMUs, and 96 ROPs.

Clock speeds also differ significantly. The GTX 1630 runs at a base of 1740 MHz and boosts to 1785 MHz, while the RX 7700 XT has a lower base of 1435 MHz but a much higher boost of 2544 MHz. The physical and power characteristics are also contrasting: the GTX 1630 is a single-slot, 145 mm long card with a 75 W TDP and no power connectors, while the RX 7700 XT is a dual-slot, 267 mm long card with a 245 W TDP and two 8-pin connectors. Finally, the bus interface differs, with the GTX 1630 using PCIe 3.0 x16 and the RX 7700 XT using PCIe 4.0 x16.

Architecture Differences

The architectural gulf between these two GPUs is immense, spanning different process nodes, designs, and feature sets. The NVIDIA GeForce GTX 1630 is built on the Turing architecture using a 12 nm process at TSMC, with a die size of 200 mm² containing 4,700 million transistors. Despite being a Turing part, it is stripped of the architecture's signature features, lacking both ray tracing and tensor cores. Its FP16 performance is rated at 3.656 TFLOPS (2:1), indicating a lossy rate conversion. It supports DirectX 12 (12_1) but not the full 12 Ultimate feature set.

In contrast, the AMD Radeon RX 7700 XT is a modern RDNA 3.0 part fabricated on a 5 nm process at TSMC. It uses a much larger 346 mm² die (Navi 32) that packs 28,100 million transistors, resulting in a dramatically higher transistor density of 81.2M / mm² compared to the GTX 1630's 23.5M / mm². The architecture is fully featured with 54 ray tracing cores, supports FP16 at a 1:1 rate matching its FP32 performance of 35.17 TFLOPS, and is DirectX 12 Ultimate (12_2) compliant. The RX 7700 XT also uses a newer PCIe 4.0 interface and supports DisplayPort 2.1 and USB Type-C outputs, whereas the GTX 1630 is limited to DisplayPort 1.4a and HDMI 2.0. These architectural differences explain the massive performance gap and position the RX 7700 XT as a future-proofed solution for next-generation gaming, while the GTX 1630 remains a legacy product for basic tasks.
