Q3 Reports for AMD/Intel/Microsoft next week!

All reports issue after close of markets on their respective dates. AMD: Tuesday, Oct. 24. Word on the Street: Expecting EPS of $0.06 (yay profits!). I'd almost expect them to top that without too much trouble based on all their product launches in Q3. Intel: Thursday, Oct. 26. Word on the Street: E...

Snapadoodle-Doo WPA2 is Borked

So the most widely deployed and modern security protocol for 802.11 networks is WiFi Protected Access v2 (WPA2) . If you use 802.11, then chances are you are using some form of this protocol for security. But unfortunately, there has been a major breach of WPA2 at the protocol level. This isn't just...

Re: Ideal Nvidia card to drive a 1440p 60Hz display?

I'd either go with a GTX-1060 if you want the more economical solution or jump up to the GTX-1080 (that can be had for under $500 if you look for the right sale) simply because the 1070's still are commanding inflated prices due to mining. The GTX-1080 with GDDR5X memory (that is bad for mining) is ...

Re: Vega is [also] overpriced because AMD has manufacturing problems

And that's just poor design and planning from AMD for gaming, both in unoptimized architectures and the exceedingly poor decision to go with HBM/HBM2. Yet AMD dominates in HPC / compute intensive workloads. When you only have the budget for one fabbed design, you make it count. I think the P100 and...

Each chip provides up to 256 threads simply because it has 32 cores and up to 8 threads per core so 32 * 8 = 256. That's all. If you want to really spend money you can buy a multi-socket system that hosts multiple chips too.
