Amd a10

     

AMD"s new A10-7890K represents the very top of the low-cost APU family. We"re answering whether it can breathe new life into the line via online gaming, or if its small cloông xã rate bump just isn"t worth more money compared lớn the A10-7870K.

The Kaveri architecture, & its small evolution khổng lồ Godovari, is as mature as it can possibly be. However, AMD decided to lớn give sầu its fans an encore. What"s supposedly makes this possible are small improvements to the 28nm process, which is plausible given AMD"s long history with these APUs and their architectures.

A second explanation for AMD"s A10-7890K APU hitting a higher 4.1GHz base frequency & screaming 4.3GHz peak Turbo Chip Core clock rate is the bundled Wraith cooler. It offers greatly improved thermal performance compared khổng lồ the old stoông xã heat sink & tín đồ.



AMD"s Wraith cooler is designed khổng lồ giảm giá khuyến mãi with up khổng lồ 125W of waste heat. Consequently, it shouldn’t have sầu any trouble with AMD"s 95W APU (though, in fact, the -7890K actually exceeded 125W in some of our testing).


Thanks to lớn the clock rate bump, AMD"s new APU ends up offering a theoretical 1.02 TFLOPS of compute performance, crossing the 1TFLOPS threshold so long as there"s no graphics workload. We have sầu a special demo just for this scenario, & it"ll show why it"s so hard for AMD"s APUs to lớn strike a good balance between their host and graphics processing capabilities.



Before we introduce our chạy thử PC, which we configured specifically for AMD"s target group, let"s take a look at the most important members of AMD"s x86 Steamroller-based family:

Building A PC For Online Gaming

Working over an open bench table does get boring after a while, so we decided to take AMD at its word & build a PC around its APU that"s both inexpensive and offers optimal performance for games like Dota 2. This system is the foundation for all of today"s benchmarks.

We settled on an ATX motherboard, since we just couldn"t find a suitable alternative. It"s just not that easy lớn find a compact platform with a Socket FM2+ interface và DisplayPort connectivity. Of course, DisplayPort was required for testing FreeSync. Our 24-inch AOC G2460PF is perfect for this kind of cài đặt.



If you can live sầu without FreeSync, there are good motherboard alternatives. For instance, you"ll find mini-ITX boards for small systems selling right around $50.


After a discussion with Caseking, we decided lớn go with the Aerocool GT-RS ATX Cube chassis. It"s a relatively inexpensive dual-chamber enclosure that toes the line between mid-tower & cube. Its $75 street price should work for lower budgets, too.


To complete our light gaming PC, we used a DVD drive sầu that can be installed vertically và an inexpensive 240GB SSD from Crucial. This setup, or a variation thereof, should be perfect for occasional gamers, so long as they understand the limitations of AMD"s APUs & are willing khổng lồ live sầu with them. As the story progresses, we"ll go inlớn more depth on what exactly those limitations are.
