The finer distinctions between DDR and GDDR can easily be masked by the impressive on-paper specs of the newer GDDR5 standards, often inviting an obvious question with a not-so-obvious answer: Why can’t GDDR5 serve as system memory?
In a simple response, it’s analogous to why a GPU cannot suffice as a CPU. Being more incisive, CPUs are comprised of complex cores using complex instruction sets in addition to on-die cache and integrated graphics. This makes the CPU suitable for the multitude of latency sensitive tasks often beset upon it; however, that aptness comes at a cost—a cost paid in silicon. Conversely, GPUs can apportion more chip space by using simpler, reduced-instruction-set based cores. As such, GPUs can feature hundreds, if not thousands of cores designed to process huge amounts of data in parallel. Whereas CPUs are optimized to process tasks in a serial/sequential manner with as little latency as possible, GPUs have a parallel architecture and are optimized for raw throughput.
While the above doesn’t exactly explicate any differences between DDR and GDDR, the analogy is fitting. CPUs and GPUs both have access to temporary pools of memory, and just like both processors are highly specialized in how they handle data and workloads, so too is their associated memory.
AOC is readying a multiplicity of gaming displays aimed at different price segments. All the gaming monitors belong to AOC’s AGON family and are largely similar aesthetically speaking, with dissimilarities chiefly in the panel types and feature sets. We’ll provide an overview below.
AOC is introducing two new curved displays to supplement their existing curved gaming monitors. The new displays both have 1800R curvature with a 16:9 aspect ratio, as well as VA panels capable of 144Hz refresh rates.
Cloudflare has disclosed a bug within their code that has resulted in a massive memory leak, dumping user data into the wild. For those unaware, Cloudflare is an internet proxy and web performance service aimed at protecting websites and associated user data from malicious activity—making a security disaster like this acutely ironic.
Between its visit to the White House and Intel’s annual Investor Day, we’ve collected a fair bit of news regarding Intel’s future.
Beginning with the former, Intel CEO Brian Krzanich elected to use the White House Oval Office as the backdrop for announcing Intel’s plans to bring Fab 42 online, with the intention of preparing the Fab for 7nm production. Based in Chandler, Arizona, Fab 42 was originally built between 2011 and 2013, but Intel shelved plans to finalize the fab in 2014. The rebirth of the Arizona-based factory will expectably facilitate up to 10,000 jobs and completion is projected in 3-4 years. Additionally, Intel is prepared to invest as much as $7 billion to up-fit the fab for their 7nm manufacturing process, although little is known about said process.
Revisiting an article from GN days of yore, GamersNexus endeavored to explain the differences between Western Digital’s WD Blue, Black, Red, and Purple hard drives. In this content, we also explain the specs and differences between WD Green vs. Blue & Black SSDs. In recent years, Western Digital’s product stack as changed considerably, as has the HDD market in general. We’ve found it fitting to resurrect this WD Blue, Black, Green, Red, and Purple drive naming scheme explanation. We’ll talk about the best drives for each purpose (e.g. WD Blue vs. Black for gaming), then dig into the new SSDs.
Unchanged over the years is Western Digital’s affinity for deferring to colors as to identify products, where other HDD vendors prefer fantastic creature names (BarraCuda, IronWolf, SkyHawk, etc.). As stated above, Western Digital has seriously changed its lineup. The WD Green drives have been painted blue, as they’ve been folded into the WD Blue umbrella. Furthermore, the WD Blue brand has seen the addition of an SSHD offering and SSDs in both 2.5” and M.2 form factors. This in no small part thanks to Western Digital’s acquisition of SanDisk—another notable development since our last article. With that, the WD Blue brand has expanded to become Western Digital’s most comprehensive mainstream product line-up.
Other changes to the Western Digital rainbow include the expanding of WD Black, and confusingly enough, WD Green brands. Starting with the latter, Western Digital rebranded all WD Green HDDs as WD Blue, selling WD Blues under two different RPMs, but recently reentered the SSD market with both. However, the WD Green SSDs are currently unavailable, perhaps due to the global NAND shortage. Likewise, the WD Black series has spilled over into the realm of NVMe/PCIe based storage and WD Black HDDs have expanded capacities up to 6TB; that’s quite a change from the 4TB flagship model we covered back in 2014. Lastly, there is WD Purple, of which we will retroactively cover here.
