Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/content/www/us/en/processors/processor-numbers.html for details.

The following list of Dell Inspiron Laptop computers hasbeentested for upgrade to Windows11. If your computer model is not listed, Dell will not test the device, and drivers will not be updated for that model. The following list of Dell XPS desktop computers has beentested for update to Windows11 build 22H2. If your computer model is not listed, Dell will not test the device, and drivers will not be updated for that model. The following list of Dell Inspiron Desktop computers hasbeentested for upgrade to Windows11. If your computer model is not listed, Dell will not test the device, and drivers will not be updated for that model.The outside of the unit is dotted with I/O ports, both legacy and current interfaces: PS/2 (for old mice and keyboards), a pair of DisplayPorts, serial port, audio, and 10 USB 2.0 ports. Unfortunately, there isn't a USB 3.0 port to be found, but then again both users and makers of enterprise-class machines don't embrace newer technologies right away. One thing that is missing in this high-end machine is an eSATA port. Users that deal in a lot of data (databases, graphics, etc.) may have already transitioned to eSATA for fast storage. Multi-GB files take a lot less time to access when using eSATA or USB 3.0.

Intel® Iris® Xe Graphics only: to use the Intel® Iris® Xe brand, the system must be populated with 128-bit (dual channel) memory. Otherwise, use the Intel® UHD brand. The following list of Alienware desktop computers hasbeen tested for upgrade to Windows11. If your computer model is not listed, Dell will not test the device, and drivers will not be updated for that model. Processors that support 64-bit computing on Intel® architecture require an Intel 64 architecture-enabled BIOS.The following list of Dell Inspiron Desktop computers hasbeentested for update to Windows11 build 22H2. If your computer model is not listed, Dell will not test the device, and drivers will not be updated for that model. Unsurprisingly, then, the new Core i7-2600K absolutely hoses its progenitor, the Core i7-870. We're talking 25 to 30 per cent more performance absolutely, positively everywhere.
