The Best CPUs for System Shock 2

Five processors compared, from the Ryzen 5 5500 to the Ryzen 5 8600G, with the trade-offs of each named.

12 min read5 products evaluated

System Shock 2 does not push current hardware, so this guide is about the lowest-cost processor that suits a wider library. Every pick cost $200 or less, ordered from the lowest price.

Our comparison rests on published figures for L3 cache, max boost and cores / threads; where a maker leaves out L3 cache, we say so, and no figure here comes from our own testing.

Our Picks

AMD Ryzen 5 5500

Lowest Price Here1 of 5

AMD Ryzen 5 5500 on Amazon (opens in a new tab)

The Ryzen 5 5500 is the cheapest six-core chip here.

Best for

Buyers who would rather put the savings elsewhere than into the Ryzen 5 5500F.

Skip if

Choose another pick if you can't accept this: 6 cores leave less headroom for streaming alongside games.

Why we like it

It has a smaller 16MB L3 cache and runs PCIe 3.0, which matters little for a budget graphics card. On L3 cache it ties with the Ryzen 5 8600G at 16MB. On boost clock it ties with the Ryzen 5 5500F at 4.2GHz.

It matches the Ryzen 5 5500F, the Ryzen 5 5600GT and the Ryzen 5 8600G on core count (6 cores). It shares DDR4 memory with the Ryzen 5 5500F and Ryzen 5 5600GT; the Ryzen 5 8600G goes with DDR5 memory. It also comes with a Wraith Stealth cooler in the box.

It was the cheapest of the group when we checked; the Ryzen 5 5500F was the next step up. The main gap: no integrated graphics, unlike the Ryzen 5 8600G. If that matters, the Ryzen 5 8600G has it.

Key dimensions & specs

  • L3 cache: 16MB
  • Max boost: 4.2GHz
  • Cores / threads: 6 cores
  • Rated power: 65W
  • Threads: 12
  • Socket: AM4
  • Memory: DDR4
  • Cooler in box: Yes
  • Integrated graphics: No

Pros

  • 65W rating suits a modest air cooler
  • Wraith Stealth cooler in the box
  • One of the cheapest six-core desktop chips
  • The cheapest way into this group, below the Ryzen 5 5500F

Cons

  • 6 cores leave less headroom for streaming alongside games

  • No integrated graphics, so a graphics card is required
AMD Ryzen 5 5500F

Also Consider2 of 5

AMD Ryzen 5 5500F on Amazon (opens in a new tab)

The Ryzen 5 5500F is built around a Wraith Stealth cooler in the box, with DDR4-3200 support and 19MB of cache on top.

Best for

Buyers who want Wraith Stealth cooler in the box.

Skip if

Look at the others if this bothers you: 6 cores leave less headroom for streaming alongside games.

Why we like it

On the spec sheet, it offers a 4.2GHz boost clock and offers a 6 cores core count. On boost clock it ties with the Ryzen 5 5500 at 4.2GHz. It matches the Ryzen 5 5500, the Ryzen 5 5600GT and the Ryzen 5 8600G on core count (6 cores).

It drops into an AM4 board with DDR4 memory; older B450 and X470 boards need a BIOS that supports this chip, so check the support list before swapping. Its price falls between the Ryzen 5 5500 and the Core Ultra 5 225F, based on our last check. Buyers who need a confirmed L3 cache should compare it with the Core Ultra 5 225F, which offers 22MB.

Intel Core Ultra 5 225F

Largest Game Cache3 of 5

Intel Core Ultra 5 225F on Amazon (opens in a new tab)

The Core Ultra 5 225F is a locked ten-core LGA1851 chip.

Best for

Players chasing 1% lows in simulation and esports titles.

Skip if

Worth skipping when no integrated graphics, so a graphics card is required is a problem.

Why we like it

It suits a budget Intel build that will pair with a B860 board. On L3 cache it leads this guide at 22MB, ahead of the Ryzen 5 5500 (16MB). On boost clock it sits mid-pack at 4.9GHz: the Ryzen 5 8600G offers 5GHz, and the Ryzen 5 5500F comes in at 4.2GHz.

Its 10 cores core count is the highest here; the Ryzen 5 5500 comes next at 6 cores. An LGA1851 socket is unique to it among these picks, while the Ryzen 5 5500F uses an AM4 socket. You also get 6 P-cores plus 4 E-cores and PCIe 5.0 and 4.0 support on Intel 800-series boards.

On price it sat third of 5, between the cheaper Ryzen 5 5500F and the pricier Ryzen 5 5600GT, at the time of writing. The maker doesn't give its rated power; if that figure matters, the Ryzen 5 5500 offers 65W.

Key dimensions & specs

  • L3 cache: 22MB
  • Max boost: 4.9GHz
  • Cores / threads: 10 cores
  • Socket: LGA1851

The Ryzen 5 5600GT is built around integrated Radeon graphics, with a Wraith Stealth cooler in the box on top.

Best for

Buyers who want integrated Radeon graphics.

Skip if

Skip it if this is a deal-breaker for you: 6 cores leave less headroom for streaming alongside games.

Why we like it

On the spec sheet, it offers a 4.6GHz boost clock and offers a 6 cores core count. Its 4.6GHz boost clock ranks third of 5 here, behind the Ryzen 5 8600G (5GHz) and ahead of the Ryzen 5 5500F (4.2GHz). Like the Ryzen 5 5500 and Ryzen 5 5500F, it has an AM4 socket, while the Core Ultra 5 225F uses an LGA1851 socket.

It drops into an AM4 board with DDR4 memory; older B450 and X470 boards need a BIOS that supports this chip, so check the support list before swapping. It was priced above the Core Ultra 5 225F and below the Ryzen 5 8600G at the time of writing. There is no published L3 cache figure, whereas the Core Ultra 5 225F offers 22MB.

AMD Ryzen 5 8600G

Highest Boost Clock5 of 5

AMD Ryzen 5 8600G on Amazon (opens in a new tab)

The Ryzen 5 8600G pairs six cores with Radeon 760M graphics.

Best for

Buyers who put boost clock first.

Skip if

Worth skipping when 6 cores leave less headroom for streaming alongside games is a problem.

Why we like it

It can run a PC without a graphics card until you buy one. On L3 cache it ties with the Ryzen 5 5500 at 16MB. Nothing else here matches its 5GHz boost clock; the Core Ultra 5 225F comes closest at 4.9GHz.

It matches the Ryzen 5 5500, the Ryzen 5 5500F and the Ryzen 5 5600GT on core count (6 cores). An AM5 socket is unique to it among these picks, while the Ryzen 5 5500F uses an AM4 socket. You get DDR5 memory here, which sets it apart from the Ryzen 5 5500 and its DDR4 memory.

It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Ryzen 5 5600GT and the rest. The trade-off is L3 cache; for more, the Core Ultra 5 225F offers 22MB.

Key dimensions & specs

  • L3 cache: 16MB
  • Max boost: 5GHz
  • Cores / threads: 6 cores
  • Rated power: 65W
  • Threads: 12
  • Socket: AM5
  • Memory: DDR5
  • Cooler in box: Yes
  • Integrated graphics: Yes

Pros

  • 65W rating suits a modest air cooler
  • Wraith Stealth cooler in the box
  • Integrated graphics for display output without a graphics card
  • Radeon 760M integrated graphics

Cons

  • 6 cores leave less headroom for streaming alongside games
  • L3 cache trails the Core Ultra 5 225F (22MB)
  • Core count trails the Core Ultra 5 225F (10 cores)

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

What we compared
We compared five processors on L3 cache, boost clock, core count and rated power as the makers state them. Nothing was tested in-house; 3 of the 9 fields compared are stated for every pick, while L3 cache and rated power have gaps.
The shared baseline
All 5, from the Ryzen 5 5500 to the Ryzen 5 8600G, state boost clock, core count and socket.
Where the specs have gaps
The Ryzen 5 5500F and the Ryzen 5 5600GT give no L3 cache; the Core Ultra 5 225F and the Ryzen 5 5600GT give no rated power.
Price range
At our last check the picks ran from the Ryzen 5 5500 ($50 to $100) to the Ryzen 5 8600G ($150 to $250).

What to Look for in a CPUs for System Shock 2

Key buying criteria so you get the right fit the first time.

  1. Boost clock

    Across these 5 picks boost clock spans 4.2GHz (the Ryzen 5 5500F) to 5GHz (the Ryzen 5 8600G). For less, the Core Ultra 5 225F is the runner-up at 4.9GHz ($100 to $150 tier).

  2. How much core count you need

    Here core count runs from 6 cores on the Ryzen 5 8600G to 10 cores on the Core Ultra 5 225F, a 67% spread. Start with the Core Ultra 5 225F if core count decides it.

  3. L3 cache across these picks

    Here L3 cache runs from 16MB on the Ryzen 5 8600G to 22MB on the Core Ultra 5 225F, a 38% spread. The Core Ultra 5 225F is the pick for L3 cache. The Ryzen 5 5500F and the Ryzen 5 5600GT give no L3 cache figure, so 3 of 5 picks are compared here.

  4. Memory

    The Ryzen 5 5500, the Ryzen 5 5500F and the Ryzen 5 5600GT list DDR4; the Ryzen 5 8600G lists DDR5. Sort out memory before price: it splits 4 stated picks into groups of 3 and 1.

  5. Cooler in box

    The Ryzen 5 5500, the Ryzen 5 5500F, the Ryzen 5 5600GT and the Ryzen 5 8600G have it.
