    Citação Post Original de Winjer Ver Post
    O problema é que a AMD já tem o mesmo IPC. Apenas nos jogos é que perde por causa da velocidade de relógio e optimizaçoes dos CCX.
    Mas mesmo nos jogos estamos a falar de uma diferença pequena e apenas no 9900k. Nos restantes CPUs, a AMD oferece melhor desempenho pelo preço. No próximo ano a AMD já domina em todos os segmentos, incluindo jogos.
    Hoje a AMD já domina em todos os price points, com o melhor desempenho em aplicaçoes e com melhor segurança e consumos do que a Intel. Só falta mesmo os jogos e apenas no ultra high end.
    Não é o mesmo, é mesmo mais. Esta geração tem um IPC 3% superior à arquitectura Intel. Se tivermos um leap de + 10% com os Ryzen 3 daqui a uns meses, vamos ver a AMD com uma vantagem de 13%~ no IPC.

    Não estou a ver os cpus Intel fazerem 5.5 GHz para esbaterem esta diferença...

    Claro que, estas diferenças na prática não se notam em tudo. O mercado do software hoje em dia ainda vive de mais de uma década de optimização e desenho centrado na arquitectura core, logo, mesmo que a Intel ofereça um produto inferior e mais caro, em certas aplicações vai continuar a ser superior.

    Mas esta diferença vai-se esfumando cada vez mais, com o novo software a ser cada vez mais optimizado para ambas as plataformas e acredito que o forcing da nova geração de consolas será bastante precioso para o lado da AMD.

    A Intel vai ter que jogar com o preço (finalmente), porque a arquitectura Core chegou ao limite e a curto prazo não tem rigorosamente nada de "bombástico" para colocar nas prateleiras e vai-se cingir ao que já existe...o tal 4c/8t no i3, 6c/12t no i5...

    Mais um mês, mas uma dose de buracos descobertos nos CPUs da Intel.

    Intel's Cascade Lake CPUs impacted by new Zombieload v2 attack

    But unbeknownst to the world, there was a fifth MDS attack at the time, which researchers kept secret because Intel had yet to release a patch.
    Nicknamed Zombiload v2 (CVE-2019-11135), this is a variation of the Zombieload v1 vulnerability, but one that worked on Intel's newer line of CPUs, those which the company claimed had protections against speculative execution attacks baked in at the hardware level.
    According to an updated version of the Zombieload academic paper that ZDNet received this week, the Zombieload v2 attack exploits the Intel Transactional Synchronization Extensions (TSX) Asynchronous Abort operation that occurs when an attacker uses malicious code to create a conflict between read operations inside a CPU.
    This read conflict for TSX Asynchronous Abort (TAA) operations leaks data about what's being processed inside an Intel CPU.
    "The main advantage of this approach is that it also works on machines with hardware fixes for Meltdown, which we verified on an i9-9900K and Xeon Gold 5218," the research team explained in the revised version of their whitepaper.
    The only condition for a Zombieload v2 attack is that the targeted CPU supports the Intel TSX instruction-set extension, which the research team said is available by default in all Intel CPUs sold since 2013.
    The first Intel CPU series to have featured TSX support was the Haswell platform. Everything that came after is affected. Intel's Cascade Lake, which the company released in April this year, was supposed to be the company's first product that featured protections against side-channel and speculative execution attacks at the hardware level.
    Intel's response

    In an email to ZDNet, an Intel spokesperson wanted customers to know that microcode updates will be made available for Zombieload v2 on the company's website.
    Furthermore, the company added that the Zombieload v2 vulnerability (which Intel tracks as the "TAA attack" in its own documentation) is not as dangerous as it sounds.
    While all the MDS attacks can allow attackers to run malicious code against an Intel CPU, attackers can't control what data they can target and extract.
    MDS attacks, while very much possible, are inefficient when compared to other means of stealing data from a target, an opinion that other security experts have also expressed in the past.
    However, the fact that day-to-day malware gangs won't bother exploiting something as complex as an MDS attack, or Zombieload v2, that doesn't mean the vulnerabilities should be ignored. Applying these microcode updates should be a priority for everyone who manages critical infrastructure or cloud data centers.
    If users don't want to update and deal with a potential performance dip due to yet another patch for speculative execution attacks, Intel also recommending disabling the CPU's TSX support, if not used.
    More bad news

    But bad news never comes alone. The same research team who found Zombieload v1 and v2, also found an issue with Intel's original patches for the four MDS attacks disclosed in May.
    The VERW instruction set, which Intel claimed could be used to protect apps against MDS attacks that may attempt to extract data while being processed in the CPU, was incomplete and could be circumvented, the research team said.
    When we asked Intel about this issue, the CPU chipmaker acknowledged the problem and claimed that the VERW instruction set, along with the other MDS attack protections were meant to reduce the attack surface and make exploitation harder for attackers, and not as a complete patch for MDS attacks.
    A version of the revised Zombieload whitepaper will be made available on the Zombieload website later today. The research team will be presenting their revised findings tomorrow at the ACM CCS conference in London.

    Intel is bringing back a 22nm Haswell-era Pentium CPU

    Com os problemas dos 10nm e perda de capacidade de produção dos 14nm+, a Intel entrou em modo desespero e vai voltar aos 22nm....
    Se há 3 anos atrás me tivessem dito que a Intel iria chegar a este nível, não acreditava, mas aqui estamos.

    Intel will trade CPU dominance for success in new markets

    "We come to work in the morning with a 30% share with every expectation over the next several years that we will play a larger and larger role in our customers' success - and that doesn't just mean CPUs. It means GPUs, it means Al, it does mean FPGAs. It means bringing these technologies together so we're solving customers’ problems. So, we're looking at a company with roughly 30% share in a $288B silicon TAM (total available market), not CPU TAM but silicon TAM," he declared at the recent Credit Suisse conference (transcribed by Wccftech).
    Intel’s recent explorations of new markets have been met with varying success. Their Optane storage and memory devices have been intriguing and popular, but their modem business turned out to be a disastrous multi-billion dollar bust. All the while, they’ve been plagued with painful CPU shortages. Swan is placing the blame on their ambition.


    "The scar tissue really started with Moore's Law. Two times scaling factor every two years, and that's kind of the simple rule of thumb. That's worked for a very long time. And the transition from 22 to 40 nm and then 14 to 10 nm we decided that despite the fact the physics was getting more challenging, we decided to set a higher bar for ourselves in terms of performance."
    "So, the 22 to 14 is not a 2 times density, it was 2.4 and it was bumpy along the way. But it worked and that working gave us the confidence that for 14 to 10 - why don't we take the scaling factor up to 2.7?"
    Of course, by trying to jump too far ahead Intel compromised their existing 14 nm foundries and couldn’t produce enough CPUs to meet demand, which left them scrambling when they should have been focusing on emerging tech like 5G. Hopefully, the new change in culture will set them on the right path.

    Com sorte ainda vamos ver um walking dead dos processadores. Um Q6600 a bater nos 5ghz.............

    Ou a Huawei ficar em segundo e a Intel para depois...
