AMD Athlon 64 4800+ X2 - Dual Core CPU

Reviews

On the 25th of April AMD announced loads of dual core stuff. Besides the launch of the dual core 8xx series Opteron it also announced the 2xx dual core Opteron and the dual core Athlon 64 X2. Today we’re a step closer to the launch of Athlon 64 X2 but it’s not here quite yet - you’ll have to wait until June for that pleasure. If only there was a large international IT trade show that started at the end of May why, that would be the perfect venue to announce a new processor.

Until the official launch happens we won’t be able to get our hands on a fully fledged Athlon 64 X2 PC, so what we have here is a technical preview based on an AMD press kit of an Asus A8N SLI Deluxe motherboard, an Athlon 64 X2 4800+ and 1GB of Corsair 3200XL Pro memory.

There are four processors in the Athlon 64 X2 family which share a number of features with each other, and with existing models of Athlon 64. Athlon 64 X2 continues to use socket 939, the fabrication process is 90nm (.09 micron) using SOI (Silicon on Insulator), the 128-bit memory controller is compatible with PC1600, PC2100, PC2700 and PC3200 DDR, although you’d be barking mad to use anything but top notch memory, and there’s one bi-directional 1GHz Hyper Transport link. This gives an effective data bandwidth of 14.4GB/sec (8GB/sec x1 HyperTransport link + 6.4GB/sec memory bandwidth). X2 has 64KB of L1 instruction and 64KB of L1 data cache, just like Athlon 64.

The second core raises the transistor count to 233.2 million, but thanks to the 90nm fabrication process the die size is only 199 square millimetres. Compare that to the 130nm SOI Athlon 64 4000+ and Athlon 64 FX-55 which have cores that use 105.9 million transistors but which have an area of 193 square mm and you’ll see what an effective die shrink can bring to the party.

The Athlon 64 X2 4800+ has a nominal operating voltage of 1.35-1.40V and a TDP (Thermal Design Power) of 110W which compares very favourably to the FX-55 at 104W and the 4000+ at 89W.

Add in support for SSE3 and a revised memory controller to help compatibility with a broader range of memory modules and what you’ve effectively got is a pair of the new Venice cores tied together with the dual Opteron crossbar.

Security: Google, Vulnerabilities Equities Process (VEP), Quad9 and More

  • Google investigators find hackers swipe nearly 250,000 passwords a week
    Hackers are constantly trying to break into Google accounts, so Google researchers spent a year tracing how hackers steal passwords and expose them on the internet's black market. To gather hard evidence about the tools hackers use to swipe passwords, Google collaborated with University of California Berkeley cybersecurity experts to track activity on some of these markets. On Thursday, they published their results.
  • Time Will Tell if the New Vulnerabilities Equities Process Is a Step Forward for Transparency
    The White House has released a new and apparently improved Vulnerabilities Equities Process (VEP), showing signs that there will be more transparency into the government’s knowledge and use of zero day vulnerabilities. In recent years, the U.S. intelligence community has faced questions about whether it “stockpiles” vulnerabilities rather than disclosing them to affected companies or organizations, and this scrutiny has only ramped up after groups like the Shadow Brokers have leaked powerful government exploits. According to White House Cybersecurity Coordinator Rob Joyce, the form of yesterday’s release and the revised policy itself are intended to highlight the government’s commitment to transparency because it’s “the right thing to do.”

  • New “Quad9” DNS service blocks malicious domains for everyone
    The Global Cyber Alliance (GCA)—an organization founded by law enforcement and research organizations to help reduce cyber-crime—has partnered with IBM and Packet Clearing House to launch a free public Domain Name Service system. That system is intended to block domains associated with botnets, phishing attacks, and other malicious Internet hosts—primarily targeted at organizations that don't run their own DNS blacklisting and whitelisting services. Called Quad9 (after the 9.9.9.9 Internet Protocol address the service has obtained), the service works like any other public DNS server (such as Google's), except that it won't return name resolutions for sites that are identified via threat feeds the service aggregates daily.

    Blockchain has been hailed by some in the technology industry as a potential method to help improve cyber security. However, security researcher Majid Malaika warns that Blockchain can potentially be abused to enable a new form of botnet that would be very difficult to take down. Malaika detailed his Blockchain-powered botnet in a session at the SecTor security conference on Nov. 15. The overall attack method has been dubbed "Botract" by Malaika, as it abuses inherent functionality in the smart contracts that help to enable Blockchain.

Graphics: AMD and NVIDIA

  • R600 Gallium3D Shader Image Support Lands, Other R600g Patches Pending
    As a follow-up to OpenGL 4.2 Support Could Soon Land For AMD Cayman GPUs On R600g, the patches have landed in Mesa 17.4-dev Git! Plus other R600g patches are on the mailing list for review. These shader image support patches for R600g expose OpenGL's ARB_shader_image_size and ARB_shader_image_load_store for Radeon HD 5000/6000 series. In the process, this ends up taking Radeon HD 6900 "Cayman" GPUs to having OpenGL 4.2 compliance from 4.1 with the shader image support having been the last blocker. Other GPUs on R600g remain at OpenGL 3.3 due to lacking FP64 support, as outlined more extensively in that previous article.

    DCN in this context is for current the DCN 1.0 Raven Ridge family of display engines. The just-launched Vega+Zen APUs feature a new display engine and that's what this DCN code is for, which is also under a separate Kconfig tunable from the rest of AMDGPU DC.

Development of Linux 4.15

    More ARM platform upstreaming has taken place for the Linux 4.15 kernel development cycle among other ARM hardware improvements.
  • Intel Coffee Lake & Cannonlake Thermal Support In Linux 4.15
    While Intel Coffee Lake hardware is shipping already, a few bits of tardy kernel code for these "8th Gen Core" CPUs is only hitting the Linux 4.15 kernel. The Intel DRM driver is most notably enabling Coffee Lake graphics by default in 4.15, but there's also some thermal code now landing among other changes now happening. Zhang Rui sent in the thermal updates for Linux 4.15 on Thursday and they include late additions for Coffee Lake but at the same time the relevant additions for Cannonlake that will be shipping in 2018 as the next-gen Intel CPUs.
