About the Intel Core i7-840QM CPU
The Intel Core i7-840QM is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q2 2010 with a suggested retail price of $568. It is part of Intel's Core i7 lineup, which is based on the Clarksfield microarchitecture. The i7-840QM is compatible with Intel Socket G1 motherboards and is fabricated on Intel's 45 nm manufacturing process.
Memory and Cache
The Core i7-840QM supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-840QM 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 i7-840QM 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 1867.0 MHz, and it can boost up to 3.2 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 i7-840QM 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 i7-840QM has the 413th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 12.67% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 4,686 score and $568 launch price (MSRP) gives it a performance per dollar of 8.25. This is the 205th best in value for the 3DMark 11 Perf. Physics benchmark.
About the Intel Celeron J4025 CPU
The Intel Celeron J4025 is an end-of-life 2-core (2-thread) processor built for the mobile CPU market. It launched in Q4 2019 with a suggested retail price of $107. It is part of Intel's Celeron lineup, which is based on the Goldmont Plus microarchitecture. The J4025 is compatible with Intel BGA 1090 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 600 integrated graphics solution.
Memory and Cache
The Celeron J4025 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Celeron J4025 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 56 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 4 MB, is larger but slower than the L1.
Cores and Clock Speeds
The Celeron J4025 features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2000.0 MHz, and it can boost up to 2.9 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 Celeron J4025 includes an integrated graphics solution called UHD Graphics 600. 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 Celeron J4025 has the 433rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 11.58% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 4,284 score and $107 launch price (MSRP) gives it a performance per dollar of 40.04. This is the 78th best in value for the 3DMark 11 Perf. Physics benchmark.
