AMD Carrizo To Deliver The Biggest Perf/Watt Leap Ever - Coming in Q2 2022

Lisa Su, AMD's CEO, revealed that Carrizo will evangelize the largest e'er generational leap in performance-per-watt for mainstream APUs. In addition Su also confirmed that Carrizo will exist launched in the second quarter of the year. Previously the company had stated that the new APU will launch quondam in mid 2022 which includes Q2 and Q3. So the recent curtailed timing revelation indicates that testing, evaluation and qualification of the side by side generation part are going swimmingly.

Carrizo is AMD's final APU based on the Bulldozer family of CPU cores. The APU will feature AMD's latest iteration of that microarchitecture lawmaking named Excavator. It volition also feature an updated graphics cadre next, GCN for brusk, GPU architecture. Carrizo will be the commencement bear witness of AMD'southward previous promise of improving power efficiency of its processors by 25 times within the next v years.

Carrizo To Deliver the Largest Ever Generational Spring in Performance Per Watt

We plan to introduce a stiff 2022 product portfolio, punctuated by the launch of Carrizo in the second quarter. Consumer and commercial pattern win momentum for Carrizo continue to gain momentum because it will deliver the largest always generational leap in performance per watt for our mainstream APUs.

So nosotros are enthusiastic about our Carrizo launch that volition take place in the second quarter. I think if you await at, y'all know, the improvements that will come with that, HSA is one of them. We'll also have significantly improved operation in battery life in Carrizo.

Carrizo brings all of the aforementioned improvements while maintaining the same 28nm SHP Globalfoundries manufacturing process used for Kaveri. Not but that simply according to eetimes.com Carrizo as well maintains the same die area every bit Kaveri. This underlines that these improvements are a result of true innovation rather than traditional generational gains due to a more avant-garde manufacturing node.

Some of the new innovations take already been revealed past AMD. Among them is full HSA (Heterogeneous System Compages) 1.0 compliance. When information technology'due south ratified, Carrizo volition be the first always SOC to have full HSA back up. Its predecessor, Kaveri, merely supports essential features of the standard and isn't compliant with all of HSA's specifications. The evolutionary improvements of AMD's fusion roadmap tin can be seen in the prototype below. Carrizo finally delivers the last requirements for full HSA support.
In the more traditional performance improvement sense Carrizo volition behave noticeably higher clock speeds than its predecessor within the same given power envelope. This is in improver to the performance improvements gained by the new CPU and GPU cores. The improved clock speeds are partially cheers to a new intelligent voltage management technology that allows AMD to reduce the voltage required to reach the desired frequency. This is achieved past feeding the SOC merely plenty voltage for the target frequency and and then reducing the frequency momentarily when voltage dips occur to maintain system stability.

To understand why this is then effective 1 must expect at how voltage typically behaves. It's impossible to evangelize a perfect voltage that doesn't dip or spike. And so what engineers take traditionally washed to ensure arrangement stability is account for the voltage dips by increasing the voltage delivery to the SOC by an equivalent margin. For instance if we know that our voltage delivery of 1.25v typically dips to 1.245v we feed the device 1.255v so that when it dips information technology doesn't become beneath one.25v. This is to account for the voltage drib that would otherwise cause system instability.  What the AMD engineers have done hither is feed the SOC one.25v and implement a very precise voltage monitoring machinery. So that when the voltage dips to 1.245v the arrangement would recognize that and reduce the frequency for a very brief moment in which that dip occurs to maintain system stability.
The outcome is a 15% improvement in functioning for a given voltage. Essentially a 15% improvement in performance per watt.

Furthermore, recent performance benchmark leak points to a doubling in graphics performance from Kaveri to Carrizo. Allowing Carrizo to deliver the same functioning of the APU inside the Playstation four. Naturally, AMD can't confirm the validity of these benchmarks as Carrizo hasn't exist released nevertheless. Synthetic benchmarks also don't tell the whole story only never the less if AMD comes close to delivering similar performance to the next, now electric current, generation of consoles within a 45-35W power envelope, that would be an extraordinarily impressive feat.

Carrizo brings revolutionary efficiency improvements on evolutionary CPU and GPU architectures. These innovations in efficiency thankfully can be implemented in whatever futurity processor by AMD, whether information technology was a CPU, GPU or an APU. And so the prospect of seeing these innovations implemented in more competitive CPU, GPU and APU products based on AMD'south upcoming next generation x86, ARM and GPU architectures in 2022. Leaves us with fifty-fifty more excitement in anticipation of what's to come.
