There is no single measure of the performance of a computer system or its constituent parts. Benchmarks and performance tests (“benchmarks”) measure different aspects of the overall performance of computer systems and components. For example, some benchmarks measure system performance on specific tasks using commercially available software applications, such as editing a photo or video; other benchmarks use software programs created specifically to measure the performance of a system or its components. Benchmarks reflect many judgments about system configurations, workloads, and measurement methodology as to which reasonable benchmark developers may make different judgments, which may affect the results. Importantly, the actual performance any user may experience may be significantly different than the performance as measured by one or more benchmarks.
Benchmarks fall into two categories. Component benchmarks measure the performance of specific parts of a computer system, such as a microprocessor or hard disk drive. System benchmarks measure the performance of the entire computer system, including all of the components. In both cases, the performance seen in day-to-day usage generally varies from published benchmark performance. This is true for several reasons. First, components must be tested in a complete computer system, and it is not always possible to eliminate the considerable effects that differences in system design and configuration (such as the type of hard drive or amount of memory) have on benchmark results. Second, differences in software applications, operating systems, and compilers (programs used to generate executable software for a given platform) affect performance. Finally, benchmark tests are typically written to simulate the usage of certain types of computer applications, which may or may not be similar to the way that a particular user actually uses the application.
No single numerical measurement can completely describe the performance of a complex device like a microprocessor or a personal computer, but benchmarks can be useful tools for comparing components and systems. Nevertheless, the only totally accurate way to measure the performance of your computer system is to test the actual software applications that you use on your own system. The benchmark results published by Intel may be inapplicable to your component or system.
Benchmarks are only one kind of information that you may use during the purchasing process. To get a full picture of the performance of a component or system you are considering, you should consult other sources of information (such as performance information on the exact system you are considering purchasing). If you have any questions about the performance of any Intel® microprocessor, please view the detailed performance briefs and reports published by Intel.
Intel contributes to the development of benchmarks in various ways. Intel is a member of or participant in various benchmarking organizations and consortia such as BAPCo* and SPEC*, and its employees often serve in various leadership roles. Intel also contributes programming resources, technical support, and/or funding to groups that develop benchmarks.
Principled Technologies Benchmark Disclosure: Intel is a sponsor and member of the BenchmarkXPRT* Development Community, and was the major developer of the XPRT* family of benchmarks. Principled Technologies is the publisher of the XPRT* family of benchmarks. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases.
Intel is a component supplier – our customers use Intel® processors to make amazing computer products for consumers. When we announce our newest processors, we don't know yet how our customers will use them. However, the products have been in development for several years, and we have been testing them throughout the development process, so we have a good idea of what you can expect from them on some of the most common tasks for which PCs are used. But since we cannot test them before launch by purchasing and testing actual consumer products, we estimate or simulate performance using an Intel Reference Platform (an internal example new system), or by using architecture simulation or modeling.
Intel's Best Processor Ever/Intel's Best Processor Yet
Compared to previous generations of Intel® processors, the latest Intel® Core™ processors offer superior performance, significant improvement in graphics performance, longer battery life, and more computing 'horsepower' at a given wattage, in a variety of devices with screens 4" to 34". Starting from Intel's 6th generation, the latest Intel® Core™ processors offer additional hardware capability for new features of modern operating systems, such as biometric login and photographic computation. These latest Intel® Core™ processors have been optimized for performance on Windows* 10.
Explaining the Features and Benefits in New Processors
New video (4k) capability: Intel's 6th and 7th Generation Core processors (and 5th generation products with certain graphics SKUs) can now run video with resolution up to 4096x2304 @24Hz.
Hardware/Software Interaction: Hardware generally works faster than software because software has to ‘run.’ The downside to that: Hardware doesn't change as easily, so the tasks need to be well defined. Microprocessors in PCs powered by Intel's latest generation technology can handle many more tasks now than they used to. In fact, they can even get a little ahead of the software, so for some new features, we may have to wait until the operating system allows the hardware to take over that task. That's why some of the newest features are ‘coming soon.’
Instant Wake (Resume from Sleep): On the desktop side, the processor (hardware) had handled ‘resume from sleep’ and has been ‘always on, always available’ for a couple generations already (new in 4th generation). On mobile, where we have to worry about battery degradation, resume from sleep was more complicated and was handled by the operating system (software). Now we are building processors that can wake the system from sleep in less than half a second, as just part of the system specification. The PC manufacturer may need to add some other circuitry on the mother board for this feature to fully perform (i.e. device manufacturer implementation may vary). Instant Wake is an example of hardware/software interaction, therefore a system may not wake in an instant, with an older operating system, which retains control of the ‘resume from sleep’ function.
