AMD Radeon HD 7770M vs NVIDIA GeForce RTX 2060 Comparison

Head-to-Head Benchmarks

The NVIDIA GeForce RTX 2060 and AMD Radeon HD 7770M occupy vastly different tiers of the graphics hardware spectrum, and the recorded data reflects that gap clearly. The RTX 2060 posts an average benchmark score of 15290 across a broad suite of tests, while the HD 7770M manages an average of only 13536 from a single recorded test. That difference of roughly 13% in raw average terms, however, flatters the older mobile chip because the two GPUs share almost no common benchmark workload.

The RTX 2060 was tested across ten different benchmarks, including 3DMark Steel Nomad DX12, Geekbench OpenCL and Vulkan, and a full Passmark suite. Its strongest showing comes in Passmark G3D, where it scores 14111, and in Geekbench Vulkan, where it reaches 65846. The HD 7770M has just one entry in the database, Geekbench Metal, scoring 13536. That single test is not comparable to any RTX 2060 result, so a direct head-to-head in identical workloads cannot be established from the recorded data.

The RTX 2060's nearest rivals in the database include the NVIDIA GeForce GTX 580 with an average score of 15283 and a delta of 0%, the AMD Radeon 680M at 15270 with a delta of 0.1%, the NVIDIA GeForce RTX 3050 OEM at 15199 with a delta of 0.6%, and the AMD Radeon RX 7600 at 15171 with a delta of 0.8%. These figures place the RTX 2060 essentially at parity with the GTX 580, within a hair of the integrated Radeon 680M, and slightly ahead of the RTX 3050 OEM and RX 7600. The HD 7770M, by contrast, sits at 54th percentile among all GPUs, while the RTX 2060 sits at 58th percentile. That four-point percentile gap is modest, but it masks the fact that the HD 7770M's single Metal score is its only data point and its rivals include the AMD Radeon RX 9070 XT at 13543 with a delta of -0.1%, the NVIDIA GeForce GTX 570 at 13515 with a delta of 0.2%, the NVIDIA P106-090 at 13470 with a delta of 0.5%, and the AMD Radeon Pro 555 at 13407 with a delta of 1%.

In terms of raw throughput, the RTX 2060 delivers 6.451 TFLOPS of FP32 compute, while the HD 7770M delivers 691.2 GFLOPS. The RTX 2060 also shows a pixel rate of 80.64 GPixel/s and a texture rate of 201.6 GTexel/s, compared to 10.80 GPixel/s and 21.60 GTexel/s for the HD 7770M. These are not benchmark scores but specification-derived rates, and they illustrate the scale of the performance divide: the RTX 2060 processes pixels nearly eight times faster and textures more than nine times faster.

Where Each One Wins

The RTX 2060 wins in every compute-heavy and graphics-intensive scenario where the two could conceivably overlap, though in practice they target completely different use cases. The RTX 2060 is a desktop GPU built for 1080p and 1440p gaming, content creation, and ray tracing workloads. Its 6 GB of GDDR6 memory on a 192-bit bus delivers 336.0 GB/s of bandwidth, which supports high-resolution textures and modern game engines. The HD 7770M, with 1024 MB of GDDR5 on a 128-bit bus, offers 64.00 GB/s of bandwidth, a figure that limits it to older titles or low-detail settings.

For compute tasks, the RTX 2060's 1920 shading units, 120 TMUs, and 48 ROPs vastly outnumber the HD 7770M's 512 shading units, 32 TMUs, and 16 ROPs. The RTX 2060 also includes 30 RT cores and 240 tensor cores, hardware that the HD 7770M lacks entirely. That means the RTX 2060 can accelerate ray tracing and AI-based features such as DLSS, while the HD 7770M cannot. The HD 7770M's only recorded win is its efficiency profile: at 32 W TDP, it consumes one-fifth the power of the RTX 2060's 160 W TDP, making it suitable for thin-and-light laptops where thermal and battery constraints dominate.

The RTX 2060 supports DirectX 12 Ultimate (12_2), while the HD 7770M supports DirectX 12 (11_1). That difference matters for modern game features like mesh shaders and variable rate shading, which require the newer feature level. In the database, the RTX 2060's Passmark DirectX 11 score of 110 and DirectX 12 score of 53 show it can handle both APIs, while the HD 7770M has no recorded DirectX scores to compare.

Specification Differences

The two GPUs differ across nearly every specification field. The RTX 2060 uses the TU106 chip built on a 12 nm process at TSMC, containing 10,800 million transistors on a 445 mm² die with a transistor density of 24.3M per mm². The HD 7770M uses the Chelsea chip built on a 28 nm process at TSMC, containing 1,500 million transistors on a 123 mm² die with a transistor density of 12.2M per mm².

Memory configurations diverge sharply: the RTX 2060 has 6 GB of GDDR6 on a 192-bit bus with 336.0 GB/s bandwidth, while the HD 7770M has 1024 MB of GDDR5 on a 128-bit bus with 64.00 GB/s bandwidth. The RTX 2060's memory runs at 1750 MHz with 14 Gbps effective speed, while the HD 7770M's memory runs at 1000 MHz with 4 Gbps effective speed.

The core configurations are equally distinct. The RTX 2060 has 1920 shading units, 120 TMUs, and 48 ROPs, plus 30 RT cores and 240 tensor cores. The HD 7770M has 512 shading units, 32 TMUs, and 16 ROPs, with no RT or tensor cores. Clock speeds for the RTX 2060 are listed as 1365 MHz base and 1680 MHz boost, while the HD 7770M has no base or boost clock recorded.

The RTX 2060's bus interface is PCIe 3.0 x16, while the HD 7770M uses PCIe 2.0 x16. Display outputs also differ: the RTX 2060 offers 1x DVI, 1x HDMI 2.0, 2x DisplayPort 1.4a, and 1x USB Type-C, while the HD 7770M is marked as "Portable Device Dependent." The RTX 2060 is a dual-slot card measuring 229 mm in length, 113 mm in height, and 35 mm in width, while the HD 7770M has no physical dimensions recorded.

Architecture Differences

The architectural gap between these two GPUs spans two distinct eras of graphics design. The RTX 2060 is built on NVIDIA's Turing architecture, which introduced dedicated RT cores for real-time ray tracing and tensor cores for AI processing. The HD 7770M uses AMD's GCN 1.0 architecture, a design that predates dedicated ray tracing and tensor hardware entirely. The RTX 2060 has 30 RT cores and 240 tensor cores, while the HD 7770M has neither.

The manufacturing processes reflect their release dates. The RTX 2060 uses a 12 nm TSMC process, while the HD 7770M uses a 28 nm TSMC process. This process difference contributes to the RTX 2060's higher transistor density of 24.3M per mm² versus 12.2M per mm² for the HD 7770M. The RTX 2060 packs 10,800 million transistors into a 445 mm² die, while the HD 7770M fits 1,500 million into 123 mm².

API support also differs. The RTX 2060 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 DirectX feature level difference is significant: 12_2 enables features like ray tracing and mesh shaders at the API level, while 11_1 is a much older feature set. The RTX 2060 also supports FP16 compute at 12.90 TFLOPS with a 2:1 ratio, while the HD 7770M has no recorded FP16 capability.

The RTX 2060's memory type, GDDR6, offers higher bandwidth per pin and lower power per bit compared to the HD 7770M's GDDR5. The RTX 2060's 336.0 GB/s bandwidth is more than five times the HD 7770M's 64.00 GB/s, which directly impacts texture streaming, high-resolution rendering, and compute workloads. The RTX 2060 also benefits from a 192-bit memory bus versus 128-bit, and a larger 6 GB frame buffer versus 1024 MB, making it viable for modern games that exceed 2 GB of VRAM usage. The HD 7770M, with its 32 W TDP, is clearly optimized for mobile power envelopes, whereas the RTX 2060's 160 W TDP and dual-slot cooler are designed for desktop performance. These architectural differences explain why the RTX 2060 achieves 58th percentile ranking versus the HD 7770M's 54th, despite the older chip's efficiency advantages.
