Two new laptop GPUs launched in NVIDIA’s low-end MX line. This classification of products is designed to slide above the GPUs found on typical laptop CPUs by a wide enough margin to justify an extra chip, but not enough to be endorsed as part of their gaming line.
As such, pretty much the only performance number that NVIDIA provides is an “up-to” factor relative to Intel’s HD620 iGPU as seen on the Core i5-8265U. For reference, the iGPU on this specific CPU has 192 shader units running at up to 1.1 GHz. Technically there exists some variants that have boost clocks up to 1.15 GHz but that extra 4.5% shouldn’t matter too much for this comparison.
Versus this part, the MX250 is rated as up to 3.5x faster; the MX230 is rated at up to 2.6x faster.
One thing that I should note is that the last generation’s MX150 is listed as up to 4x the Intel UHD 620, although they don’t state which specific CPU’s UHD 620.
This leads to a few possibilities:
- The MX250 has a minor performance regression versus the MX150 in the “up to” test(s)
- The UHD 620 had significant driver optimizations in at least the “up to” test(s)
- The UHD 620 that they tested back then is significantly slower than the i5-8265U
- They rounded differently then vs now
- They couldn’t include the previous “up to” test for some reason
Unfortunately, because NVIDIA is not releasing any specifics, we can only list possibilities and maybe speculate if one seems exceedingly likely. (To me, none of the first four stands out head-and-shoulders above the other three.)
Like the MX150 that came before it, both the MX230 and MX250 will use GDDR5 memory. The MX130 could be paired with either GDDR5 or DDR3.
Anandtech speculates that it is based on the GP108, which is a safe assumption. NVIDIA confirmed that the new parts are using the Pascal architecture, and the GP108 is the Pascal chip in that performance range. Anandtech also claims that the MX230 and MX250 are fabricated under Samsung 14nm, while the “typical” MX150 is TSMC 16nm. The Wikipedia list of NVIDIA graphics, however, claims that the MX150 is fabricated at 14nm. While both could be right, a die shrink would make a bit of sense to squeeze out a few more chips from a wafer (if yields are relatively equal). If that’s the case, and they changed manufacturers, then there might be a slight revision change to the GP108; these changes happen frequently, and their effects should be invisible to the end user… but sometimes they make a difference.
It’ll be interesting to see benchmarks when they hit the market.
Cherry is one of the most well-known brands in the mechanical keyboard industry. The company, based in Germany, is best known for their MX key switches, which have become the gold standard in the premium keyboard market. As a result of their high standards, tight quality control, and even the occasional scarcity, “genuine Cherry key switches” has become a veritable marketing point on more than a few features lists.
Since they make their own switches, it should come as no surprise that Cherry also produces their own keyboards. Today, we’re looking at the G80-3494, a new entry in the G80-3000 line and one of the few keyboards in the United States to feature Cherry MX Silent Black key switches. Do their full-fledged boards live up to the lofty standards of their switches?
- MSRP: $149.99 (currently sale price: $111.56)
- Layout: ANSI, 104-key
- Key Switch: Cherry MX Silent Black (linear)
- Key Lifespan: 50M keystroke
- Actuation Force: 60cN
- N-Key Rollover: 14-key simultaneous
- Cable: 1.75m, non-detachable, PVC coated
- Dimensions: 470 x 195 x 44 mm
- Weight: 935g

In the universe of computer mice, Logitech is one of the best known manufacturers. This one, the Logitech MX Master Wireless Mouse, is not part of their “G Series”. At a price of $99.99 USD, or $119.99 CAD, it is their most expensive offering in that class.
The MX Master is a five button, right handed mouse. While that is not particularly exciting, one interesting feature is the horizontal scrolling tumbler on the thumb rest. The wheel on top scrolls up and down, while the one on the side can scroll left and right (or be reconfigured with Logitech's software). It is also a laser mouse that is capable of tracking on many types of surfaces, including thicker sheets of glass. It can be paired to three separate devices at once, either by Bluetooth or Logitech's proprietary receiver. Its rechargeable battery lasts about 40 days of 6 hour per day usage. Four minutes of charging yields about six hours of usage, and you can apparently even use the mouse while tethered.
The Logitech MX Master will be available in April for $99.99 USD.
