In an attempt to make their GeForce line of consumer video cards less appealing to crypto miners, NVIDIA has updated many of their GPUs with “lite hash rate” versions. These are supposed to reduce effectiveness for mining of currencies like Etherium by about 50%, without impacting game performance or other applications, but to be sure of that we put a pair of GeForce RTX 3070 cards – one with LHR and one without – to the test.
AMD and Intel have both released small revisions to their latest-gen consumer CPU lines, in the form of the Ryzen XT models and Core i9 10850K. On paper these appear to be identical to current products except for very slight adjustments in clock speed, but how do they stack up in real-world photogrammetry applications?
Picking the processor, or CPU, is one of the most important decisions when building or buying a workstation – but there are dozens of options to pick from at any given point, with varying specifications and price points, so making the right choice isn’t always clear-cut. We’ve tested all of the latest processors from Intel and AMD across three popular photogrammetry applications to help you know what the best choice is for your next system.
Over the last couple of years, several new vulnerabilities have been found in modern microprocessor architectures. Many of these have been related to speculative execution techniques used across most of Intel’s product line, and a patch was released for Windows 10 last week which was intended to address some of those weaknesses. Unfortunately, it has also reduced performance in some applications – which this article will demonstrate by comparing processing speed in three photogrammetry programs before and after the update.
Dynamic Local Mode is a new feature on AMD’s biggest Threadripper processors. These CPUs have cores grouped internally, some with direct access to system memory and some which have to communicate through those other cores to access data in memory. DLM prioritizes running code on the cores which have a direct line to the memory, helping to improve performance in situations where not all of the cores are in use. How does that translate to real-world workloads, though? Let’s take a look at two photogrammetry applications and see how the 24-core 2970WX behaves with this feature on and off.
