Intel g840: Amazon.com: Intel Pentium G840 Dual Core 2.8 GHz Intel HD Graphics Retail 2.8 2 LGA 1155 Processor

Pentium Pentium, AND AN — 39 USD

Number of cores — 2, manufactured according to 32 nm process technology, Sandy Bridge architecture.

The base frequency of the Pentium G840 cores is 2.8 GHz. The maximum frequency in Intel Turbo Boost mode reaches 2.8 GHz. Please note that the Intel Pentium G840 cooler must cool processors with a TDP of at least 65 W at stock frequencies. When overclocked, the requirements increase.

With integrated Intel® HD Graphics, the computer can operate without a discrete graphics card because the monitor is connected to the video output on the motherboard.

Benchmarks Intel Pentium G840

Game Speed ​​

Performance in games and similar applications, according to our tests.

The performance of 4 cores, if any, and performance per core has the greatest impact on the result, since most games do not fully use more than 4 cores.

The speed of caches and working with RAM is also important.

Speed ​​in office use

Performance in everyday work such as browsers and office applications.

The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.

Similarly, many professional applications such as various CAD programs ignore multi-threaded performance.

Speed ​​in heavy applications

Performance in resource-intensive tasks loading a maximum of 8 cores.

The performance of all cores and their number has the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.

At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.

Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values ​​corresponding to the processor.

Speed ​​of numerical operations

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.

We believe that a minimum of 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.

Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks. Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance.

When choosing a processor for your work, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.

Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum). A typical result is shown in the middle, the more filled in the color bar, the better the average result among all tested systems.

Benchmarks

Benchmarks were run on stock hardware, that is, without overclocking and with factory settings. Therefore, on overclocked systems, the points can noticeably differ upwards. Also, small performance changes may be due to the BIOS version.

Tests in games

FPS measured by us in popular games on Intel Pentium G840 and meets system requirements. Please note that the official requirements of developers in games do not always match the data of real tests. Also, the result is strongly influenced by the overclocking of the system and the graphic settings in the game. We test at high settings in FullHD resolution to get numbers close to real gameplay.

ArchitectureCode name for the microarchitecture generation.	Sandy Bridge
Process The manufacturing process, measured in nanometers. The smaller the technical process, the more perfect the technology, the lower the heat dissipation and power consumption.	32 nm

Model Official name.	G840
Cores The number of physical cores.	2
ThreadsNumber of threads. The number of logical processor cores that the operating system sees.	2
Multi-Threading Technology With Intel’s Hyper-threading and AMD’s SMT technology, one physical core is recognized by the operating system as two logical cores, thereby increasing processor performance in multi-threaded applications.	Missing
Base frequencyGuaranteed frequency of all processor cores at maximum load. Performance in single-threaded and multi-threaded applications and games depends on it. It is important to remember that speed and frequency are not directly related. For example, a new processor at a lower frequency may be faster than an old one at a higher one.	2.8 GHz
Turbo frequencyThe maximum frequency of one processor core in turbo mode. Manufacturers allow modern processors to independently increase the frequency of one or more cores under heavy load, due to which performance is noticeably increased. It may depend on the nature of the load, the number of loaded cores, temperature and the specified limits. Significantly affects the speed in games and applications that are demanding on the frequency of the CPU.	2.8 GHz
L3 cache size The third level cache acts as a buffer between the computer’s RAM and the processor’s level 2 cache. Used by all cores, the speed of information processing depends on the volume.	3 MB
