Frequently Asked Questions About Intel Core i7 Desktops

The Intel Core i7 is a series of high-end multi-core processors that can handle a large amount of work. Choosing the right new or pre-owned i7 desktop computer can be difficult, but eBay makes the process easier.

That depends on what you are using it for. Here is how to distinguish between different types of desktop computers:

• Gaming PCs: These computers will tend to have powerful GPUs, plenty of storage space, and some additional headroom for overclocking. Several brands, including CyperPowerPC, Alienware, and HP's Omen brands, are aimed at the gaming market.
• Business computers and workstations: Dell's Optiplex and HP's EliteDesk brands are aimed at the business and corporate market. These computers have plenty of options for expansion, security, deployment, virtualization, and management. For example, the Trusted Platform Module, which provides security and authentication through cryptographic keys, is a common feature of many enterprise-class computers.
• Consumer desktops: Most other desktop computers are aimed at casual consumers. Featuring an integrated GPU or a weaker dedicated GPU, these computers are designed for multimedia, web-browsing, and other basic features.

The Intel Core i7 spans nine different generations. Each generation tends to be more powerful than the one before it, although there is some variation within each generation. This is what you need to know when deciding on the right processor:

• Number of cores: The "core" represents a distinct processing unit on the CPU. It allows more work to be processed in parallel. Most i7 processors have four cores or, in some cases, six cores. The later generations also have some models with eight cores.
• Frequency: Measured in gigahertz, the frequency describes the speed at which the core can process a given workload. Each core has its own processing speed, which typically ranges somewhere between 3-4 GHz.

Apart from the processor, this is what you should look for in a computer:

• Storage drive: Although most desktop computers have a hard drive, some models may have an optional solid-state drive that functions as a secondary storage option. A solid-state drive tends to have a smaller storage capacity, but it can reduce lengthy loading and boot-up times.
• GPU: If you're a gamer, artist, or designer, then you will want a dedicated GPU, which has its own memory. An integrated GPU does not have its own memory, so it is not as well-suited for graphically-demanding tasks.
• Extra features: Extra features include an optical disk drive, integrated Wi-Fi, and card readers.
