AMD Radeon HD 7770M vs AMD Radeon RX 7600 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison challenge: the two GPUs share almost no overlapping benchmark tests. The AMD Radeon RX 7600 has a robust suite of measurements across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads. The AMD Radeon HD 7770M, by contrast, has only a single recorded result in Geekbench Metal. This makes a direct apples-to-apples score comparison impossible, but the available numbers still tell a decisive story about their relative standing.

Looking at the average benchmark scores, the RX 7600 sits at 15171, while the HD 7770M records 13536. That is a difference of 1635 points, or roughly 12% in favor of the newer card. The RX 7600 also holds a 57th percentile ranking among all GPUs in the database, compared to the HD 7770M's 54th percentile. While both cards sit near the middle of the overall distribution, the RX 7600's positioning is measurably higher.

The RX 7600's nearest rivals in the database include the NVIDIA GeForce RTX 3050 OEM at an average score of 15199 (a delta of -0.2%), the AMD Radeon 680M at 15270 (delta -0.7%), and the AMD Radeon Pro 560X at 15082 (delta 0.6%). This places the RX 7600 within a tight cluster of mid-range performers, essentially trading blows with these competitors. For the HD 7770M, its nearest rival is the AMD Radeon RX 9070 XT at 13543 (delta -0.1%), a rather surprising pairing that underscores how close the HD 7770M's single Metal score sits to modern parts in that specific test. The NVIDIA GeForce GTX 570 (13515, delta 0.2%) and NVIDIA P106-090 (13470, delta 0.5%) also bracket the HD 7770M closely.

The RX 7600's DirectX results show a consistent pattern. Its PassMark DirectX 9 score of 226 is the highest of its DX tests, followed by DirectX 11 at 172, DirectX 10 at 84, and DirectX 12 at 58. The DirectX 12 score being relatively low compared to older API versions is notable, but the card still handles modern workloads. Its Geekbench OpenCL score of 88051 is substantial, and the Vulkan score of 34401 further confirms its compute capability. The 3DMark Steel Nomad DX12 result of 2310 provides a modern gaming metric.

The HD 7770M, with its single Geekbench Metal score of 13536, offers no comparable data for gaming or traditional rasterization. The database shows no head-to-head benchmark results between the two cards, and the win counts stand at zero for both. This data gap is itself informative: the HD 7770M's legacy status means it has not been subjected to modern test suites, while the RX 7600 has been evaluated across the full range of contemporary workloads.

Where Each One Wins

Based strictly on the recorded data, the RX 7600 wins almost every measurable category by virtue of having measurements at all. In compute performance, the RX 7600's OpenCL score of 88051 dwarfs the HD 7770M's Metal score of 13536. The HD 7770M's only benchmark result is in the Metal API, which is not even a workload the RX 7600 was tested in. Therefore, the HD 7770M cannot claim a win in any shared test.

The RX 7600's wins spread across multiple API generations. It posts a PassMark DirectX 9 score of 226, DirectX 11 at 172, DirectX 10 at 84, and DirectX 12 at 58. These numbers, while varied, all indicate functional support for older and newer graphics pipelines. The card also achieves a PassMark G3D score of 16634 and a G2D score of 984, with a GPU compute score of 8790.

For the HD 7770M, the only win is in the subjective sense of having a Metal benchmark result at all. No other GPU on this page has a recorded Metal score, so within this comparison, it is the sole representative of that API. The 13536 Metal score is below the RX 7600's OpenCL and Vulkan scores, but the APIs are not directly comparable. The HD 7770M's nearest rival, the RX 9070 XT, is only 0.1% ahead, meaning the HD 7770M essentially matches a much newer top-tier card in that particular Metal test. This is an anomaly of the database, not a reflection of real-world gaming performance.

In terms of use cases, the RX 7600 is clearly positioned for modern gaming and compute. Its 3DMark Steel Nomad result, PassMark DirectX 11, and OpenCL scores indicate capability in current titles and productivity. The HD 7770M, with its single Metal score, is only documented for one Apple-oriented benchmark. No gaming tests, no compute tests, no DirectX results exist for it in the database. Thus, the HD 7770M cannot be said to win any use case that the RX 7600 participates in.

Architecture Differences

The two GPUs come from entirely different eras and designs. The RX 7600 uses the Navi 33 chip, built on the RDNA 3.0 architecture, under the codename "Hotpink Bonefish." It is part of the Navi III generation. The process node is 6 nm at TSMC, packing 13,300 million transistors into a 204 mm² die. The HD 7770M uses the Chelsea chip, built on the older GCN 1.0 architecture, and belongs to the London generation. Its process node is 28 nm, also at TSMC, but it contains only 1,500 million transistors on a 123 mm² die. The transistor density tells a stark story: 65.2M per mm² for the RX 7600 versus 12.2M per mm² for the HD 7770M.

Memory specifications diverge sharply. The RX 7600 has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The HD 7770M has just 1024 MB of GDDR5 on the same 128-bit bus, but its bandwidth is only 64.00 GB/s. The memory clock for the RX 7600 is 2250 MHz (18 Gbps effective), while the HD 7770M runs at 1000 MHz (4 Gbps effective). That is a massive bandwidth advantage for the newer card.

Core counts differ by a factor of four. The RX 7600 has 2048 shading units, 128 TMUs, and 64 ROPs. It also includes 32 ray tracing cores. The HD 7770M has 512 shading units, 32 TMUs, and 16 ROPs, with no ray tracing cores at all. The resulting pixel rate is 169.9 GPixel/s for the RX 7600 versus 10.80 GPixel/s for the HD 7770M. Texture rate is 339.8 GTexel/s versus 21.60 GTexel/s. FP32 compute is 21.75 TFLOPS for the RX 7600, while the HD 7770M manages only 691.2 GFLOPS. The RX 7600 also lists FP16 at 21.75 TFLOPS (1:1), a feature the HD 7770M does not specify.

The RX 7600 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The HD 7770M supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The RX 7600 uses PCIe 4.0 x8 interface, while the HD 7770M uses PCIe 2.0 x16. The RX 7600 has a TDP of 165 W, a dual-slot design, one 8-pin power connector, and a suggested PSU of 450 W. The HD 7770M is a 32 W part with no listed slot width, power connectors, or PSU requirement, and its display outputs are "Portable Device Dependent," indicating it is designed for laptops. The RX 7600 offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

The production status is Active for the RX 7600, released in May 2023, with the launch MSRP of 269 USD. The HD 7770M is end-of-life, released in April 2012. The RX 7600's predecessor is Navi II, and its successor is Navi IV. The HD 7770M's predecessor is Vancouver, and its successor is Solar System.

The Verdict

The data is unambiguous. The AMD Radeon RX 7600 is the clear performer in every measurable category. Its average benchmark score of 15171 is 1635 points higher than the HD 7770M's 13536. It has four times the shading units, 4.5 times the texture rate, and over 31 times the FP32 throughput (21.75 TFLOPS vs 691.2 GFLOPS). Memory bandwidth is 4.5 times higher (288 GB/s vs 64 GB/s). It supports more modern APIs, including DirectX 12 Ultimate and Vulkan 1.4, while the HD 7770M is limited to DirectX 12 (11_1) and Vulkan 1.2.170.

The HD 7770M, an end-of-life mobile GPU from 2012, cannot compete. Its single Metal score of 13536 is its only data point, and even that is below the RX 7600's average. The HD 7770M's nearest rival, the RX 9070 XT, is essentially tied with it at -0.1% delta, but that is a statistical oddity of the Metal test, not a general sign of parity.

For a user choosing between these two, the RX 7600 is the only sensible pick for any modern workload. It is an active product with a full suite of benchmark results, including DirectX 12, OpenCL, and Vulkan. The HD 7770M has no gaming benchmarks recorded, no compute scores beyond a single Metal test, and is no longer produced. The data simply does not support any scenario where the HD 7770M outperforms the RX 7600 in a shared workload. For legacy compatibility, the HD 7770M might have its niche, but the recorded measurements show the RX 7600 as the superior hardware across the board.
