     ViewSonic releases the bizarre VG2021w

    ViewSonic should be recognized as an innovator in its field. They were the first to feature MVA 8 ms panels, the first to propose a TN 2 ms screen, and the first to announce a 1 ms (even if it hasn’t yet seen the light of day). Once again here they are with something new:

    - a 20” 4/3 with a resolution of 1400 x 1050 pixels.

    ViewSonic defends its choice for using such a panel with : "It responds to a growing demand in the workplace for a screen with better ergonomics, a larger display surface and execellent readability for text.". You can translate “excellent readability” to mean large characters perfect for those with poor vision.

    Another part of the market may be tempted to buy this screen; those who want size for a low cost. The VG2021w is announced at a price of 419 euros, a record low for a 20” ! Despite this low price, there is still the three year on-site guarantee for exchange.

    Otherwise its characteristics are quite modest. It’s equipped with a TN 8 ms panel. It will be satisfactory for games (that like a lighter resolution than on traditional 20 « , the graphic card will be happy) with a contrast of 500:1 (and luminosity of 300 cd/m²). Viewing angles are given at 150° / 130°, normal values for a TN. One last detail, it has speakers for video conferences and VolP, according to ViewSonic.

    One of our readers, Cédric adds : A large number of mobile phones and particularly ThinkPads by ™IBM/Lenovo have a 1400x1050. It good to keep it in the same resolution while docking than without.
    Samsung already has such a screen, the SAMSUNG 203B.

    Another reader, Jean-Philippe, adds : Just so you know, this isn’t the first because Acer already offers a 20" with this resolution for a while now, the ACER 2017, available for around 350..

     The end of the A64 X2 with 1 Mo of cache ?

    AMD is about to stop production of its Athlon 64 with 1 Mo of cache. This will start with single core versions, because only the Athlon 64 3800+, 3500+, 3200+ and 3000+ with 512 Ko have been announced on this Socket, which will eventually be the only one.

    This isn’t all, however, as according to The Tech Report, AMD will give the Athlon 64 X2 4800+, 4400+ and 4000+ on the Socket AM2 and/or 939 an « end of life » status by the end of the month. Thus, only the Athlon 64 FX and Opteron will have such a cache. Of course, this has been done to simplify AMD’s production process, as well as the fact that the 2x1 Mo of L2 of a A64 X2 occupies about 45% of the die surface.

    The number of 2x1 Mo that can be engraved on the same wafer is significantly less than the number of 2x512 Ko, and this is quite important for a possible upcoming price war. It should be noted that AMD information indicating a drop in prices for the Athlon 64 X2 on 24th of July did not mention price decreases for 2x1 Mo cache models. We now know it was no mistake.

    Future AMD architecture also may have motivated this change because each of the four cores will only have 512 Ko of L2, with an additional unified L3 cache of 2 Mo. The absence of the Athlon 64 with 1 Mo of L2 per core upon its release will not attract any criticism.

    The gain with 1 Mo of L2 instead of 512 Ko is quite variable for the Athlon 64 depending on the application. Our latest information on the Socket AM2 at 2 GHz (X2 3800+ vs X2 4000+) gave us gains of 6,5% with WinRAR, 6,3% in Far Cry, 4,3% in Pacific Fighters, 1,6% with Mathematica, 1,5% in DiVX encoding, 1% MPEG2 encoding and 0.7% in 3D rendering with 3ds or Maya.

    Given the performance difference between the Core 2 Duo and Athlon 64 X2, the benefit of the megaoctet of L2 cache must not have been enough for AMD, who has since decided to change its cards’ prices instead fighting a losing battle. With the size of the first decrease which should happen on 512 Ko cache models, we could believe the sacrifice was worth it.
