New vulnerabilities are published for AMD and Intel Processors, and we get an early look at the performance of Amazon’s Graviton2 processor. Join Rich Stroffolino and Tom Hollingsworth as they discuss all the IT news of the week!
This week on the Rundown:
Google launched TensorFlow Quantum, an open-source library for prototyping quantum machine learning models, desinged to let developers create hybrid AI algorithms that use both classical computing techniques and quantum computer circuit simulations. Google says that TFQ works by taking quantum data contained in quantum bits, or qubits, and processing it with “hybrid-classical AI modelling,” to generate predictions about quantum algorithms. Microsoft’s Azure Quantum and IBM’s Q both offer similar services.
At AMD’s Financial Analyst Day, the company announced Compute DNA, a new GPU archtecture otpimized for data center compute workloads. CDNA will include the second-gen AMD Infinity Architecture to provide a high-bandwidth, low-latency interconnect between GPUs and CPUs, with unified memory across both, optimized for machine learning and high performance computing workloads. AMD expects to launch the new architecture in the summer.
A vulnerability that impacts the Intel Converged Security and Management Engine (CSME) is worse than originally thought and a patch from May 2019 does not fully fix the issue. The CSME cryptographically verifies and authenticates all firmware running on a system. Mark Ermolov from Positive Technologies found the bug can be exploited by malware with root privileges to recover the chipset key and grant an attacker access to everything on a device. Previously it was thought physical access was needed to exploit the vulnerability. For sensitive systems the only recourse is to replace the hardware. Only Intel 10th-generation chips are free of the vulnerability.
Anandtech published a performance preview of Amazon’s Graviton2 processor, it’s 2nd generation ARM server chip that they’ll offer in EC2 instances. I though this was an interesting comparison to our conversation about Ampere’s recently announced 80-core ARM CPU. Graviton2 will offer up to 64-cores per socket, but with slower clock speeds and using less than half of the power of Ampere’s Altra. Anandtech points out that Graviton2 is essentially a reference ARM Neoverse N1 platform, and offers 40% cheaper performance compared to existing x86 offerings. This may change as AMD’s Rome platform begins rolling out.
