The Core i7-12700H is the lowest chip in the stack that still provides the full complement of CPU cores found in Intel's H-series die, making it a compelling option. Like prior Intel products, the default TDP for this chip is 45W, though many laptop OEMs will have modes to enable higher long-term power limits. The P-cores are clocked at 2.3 GHz base and 4.7 GHz boost, while the E-cores get a 1.7GHz base and 3.5 GHz boost clock. The 12700H packs 6P cores and 8E cores for a total of 20 processor threads, along with 24MB of 元 cache and a 96 execution unit GPU. We expect the Core i7-12700H that we're reviewing today to become the most widely used chip in Intel's line-up, like the Core i7-11800H and Core i7-10750H before it, slotting right into a huge range of mid and upper-mid range gaming and productivity systems. Intel claims these new processors should be the fastest ever seen for mobile computing and we'll be exploring that later in our benchmarks. The Alder Lake H-series targets high performance laptops, while also bringing a range of new platform advantages, including DDR5 support, a beefier Xe integrated GPU and other connectivity improvements. This is our first look at 12th-gen Core mobile processors, starting with the Core i7-12700H.Īs we've discussed at length in our desktop Alder Lake reviews, this hybrid approach has been reasonably effective on desktop machines, but the dual architecture approach should really come alive in constrained form factors like laptops, where power consumption and efficiency are key. (1.0) means incomplete Vulkan 1.0 support.Alder Lake is Intel's first serious step into the world of hybrid architectures, combining a new high-performance CPU architecture (P-Cores), with smaller efficient cores also known as E-cores, for better performance and enhanced performance per watt.Each Subslice contains 6 or 8 (or 10 in Haswell GPUs) EUs and a sampler, and has 64 KB shared memory.Only one of the FPUs supports 32-bit integer instructions. Since the throughput of FP64 instructions are 2 cycles, the FP64 FLOPS is a quarter of the FP32 FLOPS.
One supports FP32 and FP64, and the other supports only FP32. Each EU contains 2 × 128-bit FPUs and has double peak performance per clock cycle compared to previous generation.Main article: Intel Graphics Technology § Gen7 Specifications of Intel HD Graphics series Graphics The entire GPU shares a sampler and an ROP.Double peak performance per clock cycle compared to previous generation due to fused multiply-add instruction.Main article: Intel Graphics Technology § Gen6 Specifications of Intel Gen5 graphics processing units Name Hierarchical-Z compression and fast Z clear.Each EU has a 128-bit wide FPU that natively executes eight 16-bit or four 32-bit operations per clock cycle.Integrated graphics chip moved from motherboard into the processor.Main article: Intel Graphics Technology § Gen5 Each EU has a 128-bit wide FPU that natively executes four 32-bit operations per clock cycle.Full hardware DirectX 10 support starting with GMA X3500. The last generation of motherboard integrated graphics. Variable-Length Decoding (VLD) + iDCT + MC (Full) Intel's first DirectX 9 GPUs with hardware Pixel Shader 2.0 support. These chips added support for texture combiners allowing support for OpenGL 1.3. Intel marketed its second generation using the brand Extreme Graphics. Optional external MPEG-2 decoder via Video Module Interface
