About the Intel Core i7-720QM CPU
The Intel Core i7-720QM is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q3 2009 with a suggested retail price of $364. It is part of Intel's Core i7 lineup, which is based on the Clarksfield microarchitecture. The i7-720QM is compatible with Intel Socket G1 motherboards and is fabricated on Intel's 45 nm manufacturing process.
Memory and Cache
The Core i7-720QM supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-720QM has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 6 MB.
Cores and Clock Speeds
The Core i7-720QM features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1600.0 MHz, and it can boost up to 2.8 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The Core i7-720QM does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
Benchmark Performance & Value
The Core i7-720QM has the 461st best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.64% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 3,936 score and $364 launch price (MSRP) gives it a performance per dollar of 10.81. This is the 188th best in value for the 3DMark 11 Perf. Physics benchmark.
About the Intel Core i7-8665U CPU
The Intel Core i7-8665U is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q4 2018 with a suggested retail price of $409. It is part of Intel's Core i7 lineup, which is based on the Whiskey Lake microarchitecture. The i7-8665U is compatible with Intel BGA 1528 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 620 integrated graphics solution.
Memory and Cache
The Core i7-8665U supports DDR3, DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-8665U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.
Cores and Clock Speeds
The Core i7-8665U features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1900.0 MHz, and it can boost up to 4.8 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The Core i7-8665U includes an integrated graphics solution called UHD Graphics 620. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.
Benchmark Performance & Value
The Core i7-8665U has the 353rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 18.27% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 6,758 score and $409 launch price (MSRP) gives it a performance per dollar of 16.52. This is the 172nd best in value for the 3DMark 11 Perf. Physics benchmark.
