AMDĪMD is only offering two CPUs in this category today: An 8-core, 16-thread Ryzen 7 4800H with a boost clock of 4.2GHz and base clock of 2.9GHz, and a 6-core, 12-thread Ryzen 5 4600H with a boost clock of 4GHz and base clock of 3GHz. Typically labeled as “H-class,” these laptops have far more powerful 45-watt chips and tend to slot into heavier laptops. AMD claims performance per watt has basically doubled over Ryzen 3000 chips.ĪMD’s second set of Ryzen 4000 CPUs play in the heavier gaming and content creation arenas. The new Ryzen chips do support LPDDR4X RAM which should greatly help the platform’s performance with greater memory bandwidth, better battery life, and improved standby times. So take any vendor numbers with a grain of salt as they’re likely to change, company officials said. AMDįor its part, AMD said we’re in the early stages of new laptops based on Ryzen 4000 chips and a lot more tuning has to be done before judgement should be passed. Although we have seen some early Ryzen 4000 battery life specs from laptop vendors that don’t look particularly good, we’ve also seen some that look reasonable. That’s a particular sore point, as the Ryzen 3000-series hasn’t adjudicated itself here. Unfortunately, AMD didn’t disclose hard details on just how well Ryzen 4000 chips compare to Intel’s designs. Ruh roh: Battery life is TBDĪll out performance isn’t the only factor in laptops though-battery life matters too. With the Ryzen 7 4800U, AMD said, consumers can have their cake and eat it too by getting better graphics performance and better multi-core performance. Although Intel has looked down on using 3D modeling as a measuring stick for thin and light laptops, AMD’s performance in multi-threading likely means big wins elsewhere too. Ryzen 7 has more coresĪs Intel’s “Ice Lake” 10th-gen Core chips tops out at four cores, it’s no surprise that the Ryzen 7 4800U will outrun the Core i7-1065G7 to the tune of 90 percent in multi-threaded performance using Maxon’s Cinebench R20 benchmark. But single-threaded performance is just part of it. It’s finally hoping to dethrone Intel’s mobile chips, and if what AMD claims is true, it’s happening.ĪMD said the Ryzen 7 4800U, for example, will offer about a 4 percent advantage over Intel’s most advanced 10nm-based Ice Lake Core i7-1065G7 in single-threaded performance. AMD said a Ryzen 7 with 8 compute units actually outperforms its previous Rymobile chips, which had 11 compute units. The newer Ryzen 7 4000’s graphics cores actually offer 59 percent more performance per compute unit over the older Ryofferings, the company stated.ĪMD isn’t aiming at older Rythough.
