A comparison of quad-core server CPUs: For anyone looking to buy a workstation or server CPU, quad-core CPUs have become mainstream. Therefore it's important to know what you're getting for the money so I've compiled a chart with general purpose computing performance using the SPEC CPU database with the highest scores as of December 28,...; Tags: Quad-core, Memory Bandwidth, Server, Dual Processor, Advanced Micro Devices Inc., CPU, Intel Corp., Chip, TLB, SPECint, SPECfp, Processors, Semiconductors, Hardware, Components, George Ou; Blog posts 2008-01-02
Intelligent Packet Discard Policies for Improved TCP Queue Management: Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm QSDRR preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher...; Tags: Packet, Memory Bandwidth, TCP, QSDRR, Tcp/Ip, Routers & Switches, Networking; White papers 2007-01-01
TCP Offload Through Connection Handoff: This paper presents a connection handoff interface between the operating system and the network interface. Using this interface, the operating system can offload a subset of TCP connections in the system to the network interface, while the remaining connections are processed on the host CPU. Offloading can reduce computation and...; Tags: Network, Handoff, Operating System, Memory Bandwidth, Association For Computing Machinery, TCP, Tcp/Ip, Networking; White papers 2006-04-21
memory bandwidth and the Performance of Scientific Applications: A Study of the AMD Opteron Processor: The goal of this paper is to evaluate the memory subsystem performance of the AMD Reference Design Kit RDK, "Quartet", a four-CPU system based on the AMD Opteron processor.

Exploring Real Time Multimedia Content Creation in Video Games: Video games represent a class of media applications for which creating video content is as important as displaying it. This paper compares video games running on an Apple Macintosh G5 to DVD playback and the QuickTime media player. Performance monitor counters have been used to find the IPC, the L1...; Tags: Multimedia, Memory Bandwidth, Video Game, Video, Corporate Communications, Games, Marketing, Personal Technology; White papers

Feedback Directed Prefetching: Improving the Performance and Bandwidth-Efficiency of Hardware Prefetchers: High performance processors employ hardware data prefetching to reduce the negative performance impact of large main memory latencies. While prefetching improves performance substantially on many programs, it can significantly reduce performance on others. Also, prefetching can significantly increase memory bandwidth requirements. This paper proposes a mechanism that incorporates dynamic feedback...; Tags: Performance, Memory Bandwidth, Hardware, Performance Management, Human Resources, Workforce Management; White papers

Fight card: AMD Radeon 4800 vs. Nvidia GTX 200: The high-end graphics card market isn't the straightforward, mano-a-mano battle it used to be. Graphics cards with dual GPUs, systems with multiple cards in CrossFire or SLI implementations, and most recently hybrid graphics have all muddied the picture. Meanwhile, Intel has improved its integrated graphics and has long-term plans in...; Tags: Card, NVidia Corp., Advanced Micro Devices Inc., Graphics, Radeon, GPU, John Morris; Blog posts 2008-05-16
Photo of rumored Palm Treo 800w appears: Back in the day when I had a Palm OS Treo I used to load up the custom ROMs created by Shadowmite since they took out a bunch of junk that was included by default and helped me recover some available memory. It seems he scored the first photos of...; Tags: Microsoft Windows Mobile, Palm Inc., Palm Treo, Photograph, Microsoft Windows, Palm OS, Keyboards, Operating Systems, Handhelds, Software, Hardware, Peripherals, Matthew Miller; Blog posts 2008-05-16
