Tg pro istat for mac reviews4/30/2023 ![]() The time required to trigger throttling can vary from a few minutes to more than an hour, depending on the laptop’s built-in cooling system capacity relative to the laptop’s performance capabilities, the applied workload intensity, and the ambient temperature. So to measure performance, throttling must occur in at least the CONTROL test. Supplemental cooling helps to reduce heat buildup, however, it can only improve performance when the CONTROL test has enough heat buildup to cause the system to throttle processor power and in turn cause a reduction in temperatures, speed and performance. The second post-throttling-rising-rate data set cannot be easily used for comparisons. At that point each data set can be analyzed for peaks and averages, with the first pre-throttling data set used for temperature comparisons and the third post-throttling-steady-rate data set used for power, speed and performance comparisons. Each of the data sets can be tagged with start times in the CONTROL test and then synced up with the SVALT test data to allow for accurate comparisons. If the same test is used to measure temperature and performance, then the testing data will need to be divided into separate data sets, such as 1) a pre-throttling data set, 2) a post-throttling data set with an increasing rate of throttling, and 3) a post-throttling data set with a steady rate of throttling. Possible tests on Mac laptops with Intel chips might be playing a video downloaded to the local storage drive for one to two hours, while Mac laptops with Apple Silicon M1 or M1 Pro/Max might be run single-core stress tests. If separate tests are used to measure temperatures, then the testing should apply a workload sufficient to generate heat but not so high to induce throttling. Without throttling in the CONTROL test, then the SVALT test will have lower temperatures. ![]() This means that temperatures in the SVALT test can be as high or higher than the CONTROL test when throttling occurs in the CONTROL test. While it may be counterintuitive, the reality is that effective supplemental cooling that reduces throttling can lead to more heat generation and higher processor temperatures because the processors are using more power to run faster and do more work. Supplemental cooling increases the laptop system's total cooling capacity, which allows the system to run processors at higher power for a longer period of time with little to no throttling. ![]() Depending on the testing workload and methods used, temperature and performance can either be tested and measured in separate test sessions or within the same test that divides the test results into pre-throttling and post-throttling data sets. The TYPES tab above covers this topic in greater detail.Īs described in the Laptop Throttling page, temperature and performance are directly connected and so cannot be easily tested and measured at the same moment in time. Tests conducted to measure temperature should avoid processor throttling, while tests conducted to measure performance require throttling to be present in at least the CONTROL test. If not familiar with throttling, then please read the Throttling page. Processor throttling has a dramatic impact on laptop temperatures and performance. The VARIABLES, DATA and PROCESS tabs above cover this topic in greater detail. Another test is conducted with supplemental cooling as the SVALT test, which is the test that determines the impact of supplemental cooling. One test is conducted without supplemental cooling as the CONTROL test, which is the test that determines the laptop's built-in cooling system capacity. The process of testing supplemental cooling differs from typical performance benchmark testing in the following ways:Īccurate measurement of supplemental cooling is achieved by conducting two tests with workloads and conditions that are as close to identical as possible. ![]() The guide is broken down into the following sections that cover a fundamental aspect of testing:Ĭonventional benchmark tests typically gauge performance by testing for a few minutes and then comparing test results to a database of previously conducted tests. This guide is provided for SVALT reviewers and those interested in learning how to conduct accurate and repeatable supplemental cooling tests. ![]()
