The performance should be similar to the HD 6450M and therefore modern games like Anno 2070 may only run in low detail settings. With the later two the cores can also be used for general computations like transcoding videos. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. The Tessellation performance should be improved (like the desktop 6800 series) with the new cards. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The 120 Stream processors are still based on the "old" 5D architecture similar to the 5000 series. It is based on the same Seymore chip as th 6400M series and therfore should be just a renamed Radeon HD 6450M (see for benchmarks). The AMD Radeon HD 7430M (sometimes also still called ATI Mobility Radeon HD 7430) is a laptop graphics card for entry level class notebooks.
The HD 7900M and HD 7800M has PCIe 3.0 support, while the HD 7700M only offers PCIe 2.0 support.3D Printing, 5G, Accessory, AI, Alder Lake, AMD, Android, Apple, ARM, Audio, Benchmark, Biotech, Business, Camera, Cannon Lake, Cezanne (Zen 3), Charts, Chinese Tech, Chromebook, Coffee Lake, Comet Lake, Console, Convertible / 2-in-1, Cryptocurrency, Cyberlaw, Deal, Desktop, E-Mobility, Education, Exclusive, Fail, Foldable, Gadget, Galaxy Note, Galaxy S, Gamecheck, Gaming, Geforce, Google Pixel, GPU, How To, Ice Lake, Intel, Intel Evo, Internet of Things (IoT), iOS, iPad, iPad Pro, iPhone, Jasper Lake, Lakefield, Laptop, Launch, Leaks / Rumors, Linux / Unix, List, Lucienne (Zen 2), MacBook, Mini PC, Monitor, MSI, OnePlus, Opinion, Phablet, Radeon, Raptor Lake, Renoir, Review Snippet, Rocket Lake, Ryzen (Zen), Science, Security, Single-Board Computer (SBC), Smart Home, Smartphone, Smartwatch, Software, Storage, Tablet, ThinkPad, Thunderbolt, Tiger Lake, Touchscreen, Ultrabook, Virtual Reality (VR) / Augmented Reality (AR), Wearable, Wi-Fi 7, Windows, Workstation, XPS, Zen 3 (Vermeer), Zen 4 It features 512 GCN stream processors, 32 TMUs, 16 ROPs, and 2 GB GDDR5 memory with a 128-bit memory interface. The HD 7700M is clocked at 675 MHz, with 1000 MHz (4.0 GHz GDDR5 effective) memory clock speed, amounting to 64 GB/s memory bandwidth. It features 640 GCN stream processors, 40 TMUs, 16 ROPs, and 2 GB GDDR5 memory with a 128-bit memory interface. The HD 7800M is clocked at 800 MHz, with 1000 MHz (4.0 GHz GDDR5 effective) memory clock speed, amounting to 64 GB/s memory bandwidth. Its core is clocked at 850 MHz, with 1200 MHz (4.80 GHz GDDR5 effective) memory clock speed, amounting to 153.6 GB/s memory bandwidth. The HD 7970M packs 1280 GCN stream processors, 80 TMUs, 32 ROPs, and 2 GB GDDR5 memory with a 256-bit memory interface. Users will notice the HD 7900M has basically the same specifications at the HD 7870 GPU, except with the GPU clocked at 850 MHz versus 1 GHz of the HD 7870. Taking a closure look at the HD 7000M series, we start with the HD 7900M series.
