Architecture Differences

The two cards come from very different architectural backgrounds. AMD's Radeon RX 7650 GRE is built on the Navi 33 chip, using the RDNA 3.0 architecture. It is part of the Radeon RX 7000 series and is known by the codename Hotpink Bonefish. The GPU is fabricated on a 6 nm process at TSMC, packing 13,300 million transistors on a 204 mm² die, for a transistor density of 65.2 million per mm².

NVIDIA's GeForce RTX 4070 uses the AD104 chip with the Ada Lovelace architecture, belonging to the GeForce 40 series. It is built on a 5 nm process at TSMC, containing 35,800 million transistors across a 294 mm² die, with a density of 121.8 million per mm².

The AMD card features 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA card doubles the memory to 12 GB of GDDR6X and uses a wider 192-bit interface, reaching 504.2 GB/s. The memory bandwidth advantage is significant and relevant for high-resolution textures and large datasets.

The RX 7650 GRE has 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The RTX 4070 has 5888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. NVIDIA's card also supports a boost in pixel fill rate (158.4 GPixel/s vs 172.5 GPixel/s), texture rate (455.4 GTexel/s vs 345.0 GTexel/s), and FP32 throughput (29.15 TFLOPS vs 22.08).

The NVIDIA card has a higher board power, 200 W, with a 16-pin power connector, requiring a 550 W power supply. The AMD card is rated at 170 W, uses a single 8-pin connector, and is suggested with a 450 W power supply. For system integration, the RTX 4070 uses PCIe 4.0 x16, while the RX 7650 can use PCIe 4.0 x8.

Q: Which card has a higher memory bandwidth?

A: The GeForce RTX 4070 has 504.2 GB/s, the RX 7650 GRE has 288.0 GB/s. The NVIDIA card delivers higher bandwidth due to its faster 21 Gbps GDDR6X memory versus an effective 18 Gbps on the AMD card.

Q: How do the power requirements compare?

A: The RTX 4070 has a 200 W TDP and uses a 16-pin power connector. The RX 7650 GRE has a 170 W TDP and requires one 8-pin connector.

The Verdict

Based on the benchmark and specification data, the NVIDIA GeForce RTX 4070 is the clear winner. It won both head-to-head tests by margins of 39.4% and 46.3%, respectively. Its 12 GB frame buffer, 504.2 GB/s bandwidth, and 29.15 TFLOPS FP32 compute put it in another performance class than the AMD Radeon RX 7650 GRE.

The AMD Radeon RX 7650 GRE still has its own strengths: a smaller die with far fewer transistors, a lower power envelope, a simpler 8-pin power interface, and a smaller physical footprint. It also has a lower launch MSRP. But if the goal is maximum performance, the data identifies the GeForce RTX 4070 as the superior choice.
