GDDR6X:重新想象的内存

比尔·伦道夫| 2020年9月

每一天, engineers across the globe are working to build and perfect the fastest systems possible to move data, create reality from data and create intelligence from data. These systems demand the fastest memory possible. 随着时间的推移, these system demands have continually increased, but the rate of increase has exploded over the last few years. For decades, 微米 has accepted the challenge to provide Ultra-Bandwidth解决方案 that meet and exceed the memory industry’s requirements, most recently with GDDR5X. 然而,这是昨天的新闻. 2020 problems require next level thinking — something new, something shiny, something bold. GDDR6X. 记忆重.

记忆是如何被重新想象的?

Let me provide some quick insights into the creation of the world’s fastest discrete memory.

Much of the story started back in 2006 when 微米 experts began investigating the use of multi-level signaling to extend the bandwidth of the memory interface. Signal integrity experts shared these ideas across the 微米 internal engineering teams. 在一起, they delivered proof of concept by implementing 4-level pulse amplitude modulation, 或PAM4, 在LPDDR设备上. 这是真的,而且真的起作用了!

The next step - confirm that PAM4 could easily be achieved without blowing the budget. Manufacturing the device was not the issue. 微米 has smart engineers who excel in their fields. The challenge was making it manufacturable for high-volume consumer 应用程序. 换句话说, managing system cost while still delivering the fastest discrete memory on the planet. For more background on the innovation, I refer you to the GDDR6X技术简介.

After convincing ourselves it was possible, we applied our technology to address a real-world opportunity. Our challenge was to demonstrate the concept, 包括证明点, to match what we could deliver with the requirements of the end application — consumer graphics. Engineers who understood the value of PAM4 accepted the concept and this idea resonated. 有时候,星星排列得正对. GDDR6X is the result of this innovation and collaboration. 时机很好,工作很努力. To see more detail from the 微米 fellows who made it happen, 看看这个视频.

GDDRX在哪里使用?

GAMING: First and foremost, GDDRX is used in gaming. The dramatically increased memory bandwidth of GDDR6X creates a more convincing 3D render in game. Gamers want a real-life experience based on the highest resolution, maximum frame rates and instant rendering. Realism, brought to the masses, takes the gaming experience from good to great! Our first generation of GDDR6X enables data rates to achieve system performance of greater than 1TB/s. To see more on the overview of GDDR6X, check out the video.
