AMD anuncia procesos de 7nm, incluyendo EPYC ROMA con 25% de aumento de desempeñ

AMD hizo su esperado anuncio y presentacion, en la que anuncia la nueva gama de productos basados en el proceso de 7nm de TSCM.

Desde ZEN 2 (EPYC ROMA) y anuncia ZEN3 para el 2020 y ZEN4 en el futuro.
También la plataforma de GPUS profesionales en 7nm.

Zen 2 aumenta el desempeño no solamente gracias a su nuevo nodo de proceso, sino también mejorando cosas como prefetchs, predicción, cache mas grande, mejora de FP y otros..

The road to Zen began back in 2012 when AMD first started designing Zen architecture. Zen started at 14nm, while Zen+ brought it down to 12nm with further optimizations. However, AMD felt that going down to 10nm wouldn't allow for a big enough performance boost for its customers, so the company pushed down a full process node to 7nm, which AMD thinks will have a long life in its product life-cycle (hopefully not as long as Intel's 14nm node and the company's missteps to 10nm). Regardless, this process migration has allowed AMD to double chip density by 2X, halve power consumption, and deliver claimed boost in overall performance by 25 percent compared to its previous gen Zen+ architecture.

The move to 7nm also allowed AMD to make the following advances with its Rome-based EPYC processor core microarchitecture:

Improved branch prediction
Better instructions prefetch
Re-optimized micro-op instruction cache
Increased the size of the micro-op cache
Doubled floating point width to 256-bit
Doubled load store bandwidth
Increased dispatch and retire bandwidth
Results in maintained high throughput for all modes

As you might expect, AMD has been able to add some security enhancements with Zen 2 as well, including hardware mitigation for recently discovered Spectre CPU vulnerabilities. AMD has also increased the number of encryption keys for virtualization to allow companies to support more virtual machines. Infinity Fabric is now in its second generation, and I/O per die has been optimized to improve both latency and power. While Infinity Fabric itself is being kept on a 14nm process, the accompanying chipset for Zen will be built on 7nm.

AMD's latest EPYC processors will be facing some stiff competition in the form of Intel's Cascade Lake-SP and Cascade Lake-AP processors. Both are based on Intel's 14nm++ manufacturing process, but the former is expected to ship before year's end. The latter will ship in the first half of 2019 and will be available in two-socket configurations. Cascade Lake-AP processors will be available with up to 48 cores, which means that dual-socket systems will have a total of 96 physical cores on-board and the potential for 192 total threads.

La información en el sitio de anantech esta siendo actualizada mientras AMD anuncia nuevas ofertas, como AZURE, 64 cores por chip..
PCI EXPRESS 4.0 y otros.,,

Caballeros, con ustedes.. EPYC ROME de 64 cores..


cada CCX tiene 8 Cores, cada procesador tiene 4 x 16. Para untotal de 64 cores con un IO en el centro.

y Threadripper 3000 Zen2

Ahora si, Intel parece quedar en segundo lugar definitivamente.

Considerando que están eliminando el HT, Y muchos parches mas de SPECTRE que solo afectan a intel y poco a AMD.. pues si.. Intel necesita 10nm y nuevo diseño si no se va a quedar atrás por bastante.

Especialmente que los rumores dicen que AMD puede que llegue a 5Ghz, lo cual dejaría la ventaja de intel en frecuencia en el pasado.
