AMD Live Blog: Watch Zen 4 Ryzen 7000 live here now

Lisa Su ended the live broadcast and thanked the audience.

Lisa Su teases GPU with RDNA 3 architecture. The GPU has 5nm chiplets and delivers 50% more performance per watt than existing Radeon GPUs.

Su showed off a demo of the RDNA 3 GPU running the Ryzen 9 7950X. There are no performance benchmarks, but the demo shows the GPU running the highly anticipated Liza P title from Neowiz.

Lisa shared prices for the Ryzen 7000 processors ranging from $699 to $299. The chips are available on September 27th.

Lisa Su returns to the stage reviewing performance claims. But there’s more…

Motherboards will start at $125. AMD will support the AM5 platform until at least 2025. This means it will be as long-lasting as AM4.

EXPO DDR5 modules have new profiles that allow one-click overclocking. This is very similar to XMP. 15 kits will be available at launch. The maximum speed is DDR5-6400.

AMD is moving to DDR5 with AM5 and will no longer support DDR4. AMD thinks the higher performance and capacity are worth the upgrade.

PCIe 5.0 SSDs will hit the market in October.

The X-series motherboards arrive in September, while the value-oriented B-series motherboards arrive in October. AMD also announced new B650 Extreme motherboards that have more PCIe 5.0 connectivity than the standard B650 models.

The AM5 platform takes control with its 1718-pin LGA socket. AMD increased the power supply to 230W to provide improved performance in threaded applications. It also supports PCIe 5.0 and DDR5.

AMD’s David McAfee took the stage. He’s here to talk about the AM5 platform, but he started with a summary of the successes of the AM4 ecosystem.

AM4 supports five CPU architectures in four nodes. In total, it supports 125 processors and 500 have a different motherboard design.

AMD says Zen 4 remains on schedule and proves the company can deliver on schedule. Papermaster says there will be no break in AMD’s pace of innovation.

AMD will launch its 3D V-Cache models later this year. The company also offers its stripped-down Zen 4c core, which will hit the data center market early next year.

Zen 5 is a new major redesign; will arrive in 2024.

AMD’s Zen 4 core is 54% smaller than Intel’s Alder Lake chips. It’s also 47% more efficient.

AMD has significantly improved performance and power efficiency. The N5 process provides even greater performance gains with the lower 65W models.

AMD advertises 62% lower power consumption compared to generation and 49% more performance for the same power.

AMD is working closely with TSMC to tune its architecture for the TSMC 5nm node. The result is the N5 node, which has several advantages, including a stronger 15-layer metal stack.

AMD also reduced the die area despite these improvements.

AMD added support for AVX-512, but made special allowances to prevent this from resulting in reduced frequencies. To combat this problem, AMD uses a “dual-pumped” AVX-256 implementation.

Zen 4 is an iterative improvement over Zen 3. AMD has expanded the front end and improved branch prediction, delivering up to 60% IPC gain. AMD also doubled the L2 cache and op-caches.

AMD measured a 13% IPC improvement with a wide range of workloads, including gaming. Naturally, the IPC improvement varies by workload, but is generally measured at 13%.

AMD tuned the Zen 4 architecture to expose the higher frequencies available with TSMC’s 5nm process node. AMD is also working with TSMC to develop a semi-custom N5 processor node that provides improved performance.

Papermaster outlined several new improvements, including a 13% increase in IPC, a new front-end design, support for AVX-512 and a 5nm process.

AMD CTO Mark Papermaster took the stage.

AMD says the Ryzen 5 7600X delivers up to 5% more gaming performance than the Core i9-12900K. Here we can also see the full range of Ryzen 7000 processors.

Lisa Su demonstrates the Ryzen 9 7950X running a vray rendering benchmark 62% faster than Intel’s flagship Core i9-12900K, but with 47% better performance per watt.

Su also announced three other processors: Ryzen 9 7900X, Ryzen 7 7700X and Ryzen 5 7600X.

Lisa Su says that the Ryzen 9 79750X is the fastest gaming processor in the world and that it provides up to 60% more computing performance.

Lisa Su outlined the company’s goals for its Ryzen 7000 processors, including support for PCIe 5.0 and DDR5 memory. AMD exceeded its targets for the Zen 4 core, so the company is revising its original forecast of up to 10% IPC improvement to 13%.

AMD also increased peak clock speeds to 5.7 GHz, an 800 MHz improvement over the previous generation processors.

AMD CEO Lisa Su kicked off the show by describing how the company touches the lives of billions of users every day. This will continue with four new architectures that the company will release over the next few quarters. This includes Zen 4, Zen 4C, RDNA3 and its XDNA architecture.
