Trading Laptop vs Trading Desktop at the Same Price

Here's the call I get more than any other this year: "Eddie, I've got a trading computer at home and another one at the office. Two sets of charts, two sets of layouts, two sets of logins. Every time I switch desks, I'm starting over."

That's why laptop or desktop is the fastest rising question on our sales calls. And the guys who get it wrong don't lose a little speed. They buy the same computer twice. Or they grab a laptop off a store shelf, get it home, and find out it can't run four monitors.

So let's settle it with numbers instead of opinions. I took two machines from our EZ Trading Computers lineup that cost the exact same money. One is the 18-inch Odyssey laptop. The other is the Chart Breaker desktop. Every machine we build gets a CPU benchmark test before it leaves the shop, so I have the real score for both. Then I did the thing most traders never check until it's too late: I hooked up four monitors to each one.

There are three benchmark scores in this story. The first two won't surprise you much. The third one is the laptop most traders actually buy, and that score is the reason I wrote this.

Which is faster for trading, the laptop or the desktop?

The Odyssey's CPU benchmark score comes in at 58,444. The Chart Breaker comes in at 68,894. So the desktop takes it by 10,450, and you'd think we just declared the winner.

We didn't. The floor for active trading, the number I've been hammering on for over a year, is 45,000. Below that, your platform starts hesitating exactly when you need it to be sharp. Both of these machines clear 45,000 by a mile, and the laptop clears it by more than 13,000 points. Speed isn't the tiebreaker on this question. Speed got settled before the question was even asked. I go deeper on that number in the 45,000 rule for trading computers.

The third number is the one that costs traders money

Walk into a big box store this weekend and pick up the laptop with the Core i7 sticker on the lid. You know the one, on the end cap, with the little card next to it that says "great for multitasking." Most of these machines land somewhere between 14,000 and 25,000 on the same test.

Read that again. 14,000 to 25,000. Our laptop scores 58,444. That's the gap that costs traders money, not the 10,450 points between my two machines. It's the 40,000 points between a real trading laptop and the one with the sticker. A trader on a 19,000-point machine isn't choosing between good and better. He's flying a plane with a three-cylinder engine and hoping.

Machine	CPU benchmark score	Versus the 45,000 floor
Chart Breaker desktop	68,894	Clears it easily
18-inch Odyssey laptop	58,444	More than 13,000 above
16-inch Voyager laptop	50,705	More than 5,000 above
Typical store Core i7 laptop	14,000 to 25,000	Below it

I get why people are confused. Most laptop versus desktop comparisons out there are built around gaming. A gaming machine is built for pretty frames and blowing up aliens. Your trading machine has to swallow thousands of ticks a second and redraw six charts while you're reaching for a hotkey. Totally different job, which is exactly why gaming PC specs don't match trading PC specs.

So before you go any further, find out where your machine actually stands. I built a free CPU benchmark test for traders. It takes about two minutes and hands you your number so you can put it up against 45,000. If you're sitting at 22,000 right now, this whole article changes for you.

Can a trading laptop run four monitors?

This is where I expected the laptop to fall apart. It didn't.

The Chart Breaker drives four screens straight off the graphics card. Four cables, four ports, done. Nothing clever about it.

The Odyssey drives four external monitors too, through our four-port external monitor adapter. That's a $199 part. One connection from the laptop, four screens running on the other side. Platforms open across all four, windows land where you put them, nothing goes black. Are there generic docking stations out there? Sure. Ours is one I've bench tested under live trading load with our own machines, so nobody's hunting for drivers at the open.

A port that looks like a video port is not always a video port

I built my first multi-monitor trading rig for myself back in 1995, and one thing has not changed in 30 years. On a lot of store-bought laptops, only one of those little USB-C ports runs a monitor. The others will charge your phone and run a mouse or a flash drive, but they won't light up a screen.

The only way to know is the spec sheet. If it doesn't say DisplayPort or Thunderbolt next to that port, it doesn't carry video. Most traders find out about two minutes before the open with three monitors sitting dark. I saw the same story play out when I tested six trading laptops on four monitors.

One laptop, two desks, the same four screens

Here's why that adapter matters more than it sounds. Put one at your home desk and one at the office desk. You walk in, plug in one cable, and your entire four-screen layout is sitting there waiting for you. Same charts, same hotkeys, same logins.

I had a caller a few months back, Dennis, an options trader. He called to buy a second desktop. He's got a home office plus a second office he uses two days a week, and he was about to spend six grand to own the same computer twice. I told him to buy one Odyssey and two adapters instead. Now he's got four screens at both desks, and only one set of platforms to maintain on one laptop. That's the call a spec sheet can't make for you.

Do trading laptops overheat during a full market day?

Every laptop has to deal with heat. When a laptop gets too hot, it slows its own processor down to protect itself. So the only question that matters is whether your laptop was built to handle a full trading day, or built to look thin and cool at the coffee shop.

Trading is not a short burst of work. It's six and a half hours of non-stop real-time data hammering that machine. It's an endurance event. The Odyssey is a thicker machine on purpose, because the extra thickness is the cooling system. That cooling is why the Odyssey runs at full speed through the whole session while a thin laptop starts slowing down by 10:30.

Three habits that keep a laptop at full speed

I give every laptop buyer the same three habits.

Habit	Why it matters
Keep it plugged into the wall during market hours	On battery, a laptop cuts its own power to make the battery last. You don't want that between 9:30 and 4:00 Eastern.
Set power mode to best performance	Click Start, type settings, open it, click System, then Power and battery. Under Power mode, set the plugged-in drop-down to Best performance.
Use a cooling pad	It's $25 or $30. It lifts the machine so the intakes underneath can breathe, and a couple of extra fans push air into the laptop.

The laptop that cooks itself is a quarter-inch consumer machine with one little fan in it, and there's no habit on earth that saves that one.

If you're leaning toward a laptop for sure, grab my free Complete Guide to Laptops for Traders. It covers what the ports actually have to do, what the cooling has to be, and what the number has to be before you hand anybody a credit card. It's the cheat sheet for everything in this article.

What each machine actually gives you

The Chart Breaker gives you the biggest number for your money: 68,894 at the same price. It gives you room. Three years from now you can drop in more RAM, a bigger hard drive, or a newer graphics card and keep the machine. It carries a 5-year bumper-to-bumper warranty, which tells you exactly what I think about how long that machine is going to run. If you trade from one desk and that desk never moves, that headroom is free money. Take it. Here's the Chart Breaker desktop at its current sale price.

The Odyssey gives you one machine instead of two. One set of trading platforms, one set of layouts, one set of hotkeys, one place your logins live, and the same four-screen desk at home and at the office. For a trader who splits his week, this isn't a compromise. It's a better answer than two desktops, and it costs less.

I'll say the honest part out loud. It's a big laptop, 18 inches, and it's got weight to it. That weight is the cooling, and that's the trade. It's a trade I'd make every day of the week for a machine that holds 58,444 under a live data load. Here's the 18-inch Odyssey laptop at its current sale price.

If you fly all the time and every pound counts, pick the 16-inch Voyager laptop instead. It benchmarks at 50,705, still more than 5,000 points above the 45,000 floor, and it slips easily into a carry-on.

Which one should you buy?

Let me match you up instead of ranking them.

How you trade	My pick
From two places, or you travel	Odyssey, plus an adapter at each desk
At home on four or more screens, machine never moves	Chart Breaker, not even close
You fly constantly and every pound counts	16-inch Voyager

Frequently Asked Questions

Which is best for trading, a laptop or a desktop?

It depends on where you trade, not on speed. At the same price, our Chart Breaker desktop scored 68,894 and our 18-inch Odyssey laptop scored 58,444, and both clear the 45,000 floor for active trading. If you trade from one desk that never moves, the desktop gives you more speed and room to upgrade. If you split your week between two desks or travel, one laptop with an adapter at each desk beats owning two desktops.

What benchmark score do I need to day trade?

The floor for active trading is 45,000 on our CPU benchmark test. Below that, your platform starts hesitating exactly when you need it to be sharp. Many laptops with a Core i7 sticker from a big box store land between 14,000 and 25,000, well short of it. You can check your own machine with our free benchmark test, which takes about two minutes and gives you a number to compare against 45,000.

Can you day trade on a laptop?

Yes, if it's built for it. Our 18-inch Odyssey laptop scores 58,444, more than 13,000 points above the 45,000 floor, and it runs four external monitors through a $199 four-port adapter. The key is cooling: a trading day is six and a half hours of non-stop data, and a thin laptop starts slowing down by 10:30. Keep it plugged in, set power mode to best performance, and use a cooling pad.

Is a gaming PC good for trading?

A gaming machine and a trading machine do different jobs. Most laptop versus desktop comparisons are built around gaming, where the goal is pretty frames and blowing up aliens. A trading machine has to take in thousands of ticks a second and redraw six charts while you're reaching for a hotkey. Judge any machine by its CPU benchmark score against the 45,000 floor, not by how it's marketed.

How do I know if a laptop's USB-C port can run a monitor?

Check the spec sheet. On a lot of store-bought laptops, only one USB-C port runs a monitor, and the others only charge a phone or run a mouse or flash drive. If the spec sheet doesn't say DisplayPort or Thunderbolt next to a port, that port doesn't carry video. Most traders find this out a couple of minutes before the open with three monitors sitting dark.

Why does my laptop slow down during the trading day?

Heat and power. When a laptop gets too hot, it slows its own processor down to protect itself, and on battery it cuts its own power to make the battery last longer. Keep it plugged into the wall from 9:30 to 4:00 Eastern, set the plugged-in power mode to best performance, and put it on a $25 to $30 cooling pad so the intakes underneath can breathe.
