Officials also say it’s not uniform in all applications, however, so your mileage will vary. This, AMD claims, can yield up to a 15-percent boost.
That’s now fixed, and Windows 1903 will send threads the same cluster of CPU cores when possible. This would sap some performance, as the threads would then have to deal with crossing between the two clusters of cores instead of simply dispatching both threads to the same cluster of CPU cores.
Because it was never designed for multi-die designs, it would send a second thread to a different cluster of CPU cores. In older versions of Windows, the scheduler would dispatch one thread to a city in one cluster. Remember: AMD’s CPUs are constructed with small cities of CPU cores and high-speed, but slower access between the cities of CPU cores. Yes, that larger 元-err, Game Cache will also help application performance, but no one gets excited about App Cache we guess. It also tends to boost gaming performance dramatically on the CPU, so AMD feels calling it Game Cache can help the average consumer understand its benefits. The cache, up to 70MB on the Ryzen 9 3900X, goes a long way toward reducing memory latency on the Ryzen 3000s. AVX’s impact is mostly seen in video encoding today, but it can rear its performance head elsewhere too.ĪMD has essentially doubled the 元 cache on the Ryzen 3000 chips, and the company is going for some Apple-esque marketing by calling it Game Cache. Besides doubling the floating point performance, AMD has now adopted AVX-256 (256-bit Advanced Vector Extensions) (and yes, Intel fans, we know Core has AVX-512). On an even deeper level, AMD said it has improved instruction pre-fetching, further enhanced the instruction cache and doubled the micro-op cache.
With that production technology lead, AMD breaks out a redesigned 2nd generation “Zen” core for the Ryzen 3000 that promises double the floating point performance over the previous Ryzen 2000 series, as well as a 15-percent increase in “instructions per clock” (think overall efficiency per clock).
