  • Underrated calculator
The fx-CG50 is a fairly high end non-CAS (more on this later) graphing calculator. Marketing-wise, it positions itself as a direct competitor to the TI-84 Plus CE, but that's selling it short. In terms of power, it's more similar to the non-CAS TI-Nspire CX II that it is to the TI-84 Plus CE. Here is how it stacks up compared to the 84 Plus CE: Processor speed: The fx-CG50 has a 116 MHz Hitachi SH7305 32/16-bit processor, which is a variant of the CPU that was used in the Sega Dreamcast game console. Oddly, given that this is a calculator, the SH7305 lacks an FPU. This was probably done to make it consume less power. The 84 Plus CE has a 48 MHz Zilog eZ80 16/8-bit processor (also without an FPU). On paper, the difference is massive. In practice, the Casio runs about 2 to 8 times faster than the TI on most operations. That's still significant and you can see it quite dramatically when plotting a graph. Memory: Memory is laid out somewhat differently between the two calculators. The fx-CG50 splits its memory between 61 kb of main memory and 16 Mb of "storage" memory. The "storage" memory serves both as a flash ROM and as a file system. The 84 Plus CE has 149 kb of RAM and 3 Mb of flash ROM for applications. On paper, the TI seems to have more RAM, but a lot of what the TI needs to keep in RAM, the Casio can offload to its bigger "storage" memory, keeping all of thee 61 kb free for use. Which one wins will depend on how you use it, but overall, the two are on the same order of magnitude when it comes to memory. For my use, the Casio's more flexible memory layout makes it more practical. Functionality: Both are advanced scientific calculators with almost everything you can imagine built-in or offered as an "app". Where the fx-CG50 trounces the 84 Plus CE and leaves it bleeding on the floor is that there is a free CAS system available that's a port of Xcas/Giac (the same CAS system that's the basis for the HP Prime), propelling the fx-CG50 into the CAS category of super calculators. If you don't know what CAS is, it's a software system that lets you do symbolic math and exact arithmetic. It's so powerful, that it's banned in almost every exam and even in some regular classes. Where the TI wins is in the vast ecosystem of downloadable apps for every imaginable purpose. Programming: Until recently, the Casio was a clear winner because it comes with a light version of Python built in. But TI has since added Python to the 84 Plus CE. You may still see the 84 advertised as pre-Python, but receive the Python version, however there are no guarantees that you won't get older, pre-Python stock. It used to be that the 84 Plus CE could be programmed in Z80 machine language, but after someone wrote a Z80 program that could inconspicuously disable "exam mode", TI updated the OS to prevent native code, killing one of its best features. It's possible to jailbreak the newer 84s to allow Z80 machine code, but TI could counter that at any time. The Casio, on the other hand, still allows native programming, AND there are tools available to program it (from a PC) using C++ and other languages, making it again the clear winner for programmability. Both calculators have a built-in BASIC-like language, but Casio's is horrible. If you plan to use the BASIC-like programming language, TI-BASIC is the winner by far, and it's better documented. Batteries: The TI is the winner here. It has a nice, slim cell phone style rechargeable battery. But the Casio has a feature that I haven't seen since my old HP 200LX: it can use either disposable alkaline batteries OR Ni-MH rechargeable batteries (which are not recommended for calculators that don't expressly support them). The Casio, however, doesn't recharge the Ni-MH batteries itself. They need to be recharged externally. But it's aware of them (if you tell it) and is able to report the correct charge. Price: Both the Casio and the TI are priced within $20 or $30, the Casio usually being the cheaper of the two, despite being a lot more powerful. Alternatives: Just as the TI-84 Plus CE is an upgrade of the TI-83 Plus, which is now fairly outdated, the Casio fx-CG50 is an upgrade of the Casio fx-9750GIII. However, the 9750GIII is NOT outdated. In fact, some benchmarks show it to be faster than the CG50. It has a lower resolution black-and-white screen, but in all other respects, except for a smaller 3 Mb storage space, it's practically identical to the CG50, right down to the keyboard layout. But it costs peanuts compare to the fx-CG50 or the TI-84. It will cost between a third and half of the price of the color models. I got mine on sale for $30. If you don't mind b&w graphics, it's a phenomenal value. Size: The Casio is thicker, wider, and heavier than the TI. If you're shopping for a case, you'll need one that supports oversized calculators like the Nspire CX II. The Casio won't fit in cases that are made for the TI-84. Some will not like the bulkiness of the Casio. Politics aside, if your choice is between a Casio fx-CG50 and a TI 84 Plus CE Python, the Casio would be your best option by a wide margin. But politics exist. Your school or teacher or standard exam may require the TI and bar the Casio, leaving you little choice. The course material is much more likely to be tailored to the TI. The TI is overwhelmingly the most popular calculator, so you may be surrounded by others who have the 84. This makes it easier to share information, tips, and tricks, or to seek help when you need it. ... show more

  • Best graphing calculator ever!
To start things off, I am a computer science major so I will need this a lot for math classes. This graphing calculator is cheaper than the more popular ones, have way more menu options and are so easy to navigate!! The battery life is awesome, it looks very sleek, is sturdy and overall has better features, in my opinion. It gives very accurate answers with the graphing features, which helps A LOT! Been using this since 10th grade and will continue using it for the rest of my life. ... show more

  • Beautiful and Functional Calculator
This calculator is very solidly constructed and well designed. Very legible large color display. Easy to set up with an exceptional online user Manual with excellent legibility and copious use of color. Buttons are large and have a very solid feel. Setup is exceptionally easy and virtually automatic. The moment your install the included Panasonic alkaline batteries, the calculator guides you through the setup menu. The most important and frequently used buttons are white and large. Calculations are very fast, even on complex equations. Very functional overall design, and very highly recommended. ... show more

  • TI 84 plus CE doesn’t have anything on this one
Having to use AAA batteries is worth what this calculator is capable of. Upsides: It graphs up to 20 functions in a fraction of the time of the ti 84. You can choose decimal or exact outputs for your calculations. It has statistics, spreadsheet, and even Python programming capabilities. It has an app specifically for calculating finances. It has a list of 6 different probability simulators. It has 50 or so different conversion capabilities. It has a massive list of commonly used constants in maths, physics, etc. It even has a built in periodic table with quick descriptions of where some of the elements can be found. It also has a test mode that can be activated, making it school test legal. Downsides: It’s possible to accidentally delete apps if you are unsure of what you’re doing. They can be easily recovered on Casio’s website however. It is not as user friendly as the TI series of calculators. It’s quite a bit more complicated than them, but is offset by the fact that it is capable of a lot more. Casio does have a hefty user guide online for it, which is nice if you really want to figure it all out. I am extremely pleased with this calculator. It was absolutely worth the sale price, and definitely worth its normal price. Since it can run Python programs, I’m going to try and get it to run Doom. ... show more

  • Buy the CG50 before it gets discontinued.
I was aware that the fx-CG100 would be released as the successor to the CG50, but after trying out the CG100 simulator in advance, I was surprised at how inconvenient and unintuitive the new interface was. That experience made me decide it would be wiser to purchase the CG50 before it gets discontinued. Since the CG50 shares button layout and menu structure with older models like the fx-9860 and fx-991 series, I was able to adapt quickly. With support for CAS functionality through expansion plugins, and considering the overall performance and ease of use at this price point, I'm very satisfied with my purchase. ... show more

  • Versatile and reliable. Definitely worth it. 👍
I'm in high school and just got this calculator for my geometry/trig class. My list said to get a TI84+ but I had only used casio products in the past so I really prefer their layout. Soooo worth it. Love that it is in color and the main menu has loads of features (like 15 general ones that all have subsections within them). Took me about a week to get the hang of navigating it and finding all of the key features that I need for my class, but I am so glad I went with it. Really cool graphics and sleek modern look, also the 3d graphing is a big plus. Anyways, yeah, highly recommend! PS. To get to the regular calculator feature, just go to menu and press 1. It took me a bit to figure that out so hope this helps if you are struggling to navigate it. ... show more
