About the Intel Core i7-820QM CPU
The Intel Core i7-820QM 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 $546. It is part of Intel's Core i7 lineup, which is based on the Clarksfield microarchitecture. The i7-820QM is compatible with Intel Socket G1 motherboards and is fabricated on Intel's 45 nm manufacturing process.
Memory and Cache
The Core i7-820QM supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-820QM 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 i7-820QM 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 1733.0 MHz, and it can boost up to 3.1 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 i7-820QM 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 i7-820QM has the 452nd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.82% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 4,002 score and $546 launch price (MSRP) gives it a performance per dollar of 7.33. This is the 209th best in value for the 3DMark 11 Perf. Physics benchmark.
About the Intel Core i3-1115G4 CPU
The Intel Core i3-1115G4 is a 2-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2020. It is part of Intel's Core i3 lineup, which is based on the Willow Cove-U microarchitecture. The i3-1115G4 is compatible with Intel BGA 1449 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe Graphics G4 integrated graphics solution.
Memory and Cache
The Core i3-1115G4 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i3-1115G4 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, 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 i3-1115G4 features 2 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.0 GHz, and it can boost up to 4.1 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 i3-1115G4 includes an integrated graphics solution called Iris Xe Graphics G4. 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
The Core i3-1115G4 has the 392nd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 15.08% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
